Salivary gland (SG) cancer and tumors Salivary gland (SG) cancer and tumors refer to abnormal growths within the salivary glands, which are responsible for producing saliva. These glands include the parotid, submandibular, sublingual, and numerous smaller glands within the mouth and throat. While most salivary gland tumors are benign (non-cancerous), a percentage develop into malignancies (cancerous). The diversity of cells in the salivary glands leads to various types of tumors, each with different characteristics and treatment approaches. Book Thyroid & Neck Ultrasound Types of Salivary Gland TumorsThe majority of salivary gland tumors originate in the parotid gland, with fewer arising in the submandibular and sublingual glands or minor salivary glands. Some of the common types include:- Pleomorphic Adenoma: The most common benign tumor, usually found in the parotid gland.- Warthin's Tumor: Another benign tumor that typically occurs in the parotid gland, often affecting smokers.- Mucoepidermoid Carcinoma: The most common type of malignant salivary gland tumor, which can vary in aggressiveness.- Adenoid Cystic Carcinoma: A malignant tumor known for its slow growth but potential to spread to distant sites, including the lungs and bones.- Acinic Cell Carcinoma and Adenocarcinoma: Other types of malignant tumors with varying degrees of aggressiveness.- A lump or swelling in or near the jaw, or in the neck or mouth- Persistent pain in the area of the salivary gland- Difficulty swallowing or opening the mouth widely- Numbness or weakness in part of the face- Fluid draining from the ear (if the parotid gland is affected)- Older age- Radiation exposure, including previous radiation therapy- Workplace exposure to certain substances, such as nickel alloy or silica dust- Family history of salivary gland cancer (rare)- Physical Examination: Checking for lumps or areas of swelling in the head and neck.- Imaging Tests: Ultrasound, CT scans, MRI, and PET scans can help visualize the tumor's size and spread.- Fine Needle Aspiration (FNA) Biopsy: The most definitive way to diagnose salivary gland cancer, involving the extraction of cells from the tumor for examination under a microscope.- Sialography: Rarely used, this test involves injecting a dye into the salivary ducts before taking X-rays to detect tumors or blockages.- Surgery: Often the first line of treatment, aiming to remove the tumor along with a margin of healthy tissue. In some cases, lymph nodes in the neck are also removed.- Radiation Therapy: May be used post-surgery to destroy any remaining cancer cells, as a primary treatment for patients who cannot undergo surgery, or to relieve symptoms of advanced cancer.- Chemotherapy: Less commonly used for salivary gland cancer and typically reserved for advanced stages or tumors that have spread to other parts of the body.- Targeted Therapy and Immunotherapy: Emerging treatments that target specific pathways or mechanisms involved in cancer cell growth and spread are being explored in clinical trials. Book Thyroid & Neck Ultrasound ConclusionSalivary gland cancer is relatively rare, and the prognosis varies widely depending on the tumor type, stage at diagnosis, and response to treatment. Early detection and treatment are crucial for improving outcomes. If you experience any persistent symptoms affecting the salivary glands, it's important to seek medical evaluation promptly.To book online select the date and time that suits you best – alternatively, please contact us with any questions via the chat, call or email links provided.Address: 27 Welbeck Street, London, W1G 8ENTelephone: 020 7101 3377 Book Thyroid & Neck Ultrasound

lymphadenopathy: Causes, Symptoms, Treatment Lymphadenopathy refers to the condition characterized by enlarged lymph nodes, which are critical components of the body's immune system. These nodes filter lymph fluid as it circulates through the body, trapping bacteria, viruses, and other foreign substances, which are then destroyed by specialized white blood cells known as lymphocytes. Lymphadenopathy can occur in just one area of the body (localized) or in multiple areas (generalized), and its presence often indicates an ongoing inflammatory response or disease process. Book Lymph Node Ultrasound Causes of LymphadenopathyThe causes of lymphadenopathy can be broadly classified into infectious, inflammatory, and malignant:- Infectious Causes: Bacterial infections (like streptococcus, staphylococcus, tuberculosis), viral infections (such as HIV, Epstein-Barr virus, cytomegalovirus), fungal infections, and parasitic infections can cause lymph node enlargement as the body attempts to fight off these pathogens.- Inflammatory and Autoimmune Causes: Diseases such as lupus, rheumatoid arthritis, and sarcoidosis can lead to lymphadenopathy as part of the immune response to inflammation.- Malignant Causes: Cancers that originate in the lymphatic system itself, like lymphomas, or cancers that metastasize to lymph nodes from other sites can cause lymphadenopathy. Leukemia can also cause enlargement of lymph nodes due to the proliferation of leukemic cells.- Fever and night sweats (common in infections and lymphoma)- Weight loss (seen in cancer and certain infections)- Fatigue and general malaise- Pain or tenderness in the affected lymph nodes (more common with infections)- Symptoms specific to the underlying cause, such as a sore throat in infectious mononucleosis or joint pain in rheumatoid arthritis- Medical History and Physical Examination: To assess symptoms and identify potential exposure to infectious agents or risk factors for cancer.- Blood Tests: Including complete blood count (CBC) and specific tests for infectious agents or autoimmune markers.- Imaging Studies: Such as ultrasound, CT scans, or MRI, to evaluate the size, number, and characteristics of enlarged lymph nodes and to look for possible sources of infection or malignancy.- Biopsy: A definitive diagnosis often requires a biopsy of the enlarged lymph node, which involves removing a small tissue sample for microscopic examination. This can distinguish between reactive (benign) lymphadenopathy, infection, and cancer.- Infections: Antibiotics, antivirals, or antifungal medications, depending on the pathogen involved.- Inflammatory and Autoimmune Diseases: Treatment may include anti-inflammatory medications or immunosuppressive drugs.- Cancer: Depending on the type and stage, treatment options may involve chemotherapy, radiation therapy, targeted therapy, or surgery. Book Lymph Node Ultrasound ConclusionLymphadenopathy is a common and often benign condition, but it can also be the first sign of a more serious underlying disease. If you notice persistent or unexplained lymph node enlargement, especially if accompanied by other symptoms like fever, weight loss, or night sweats, it's important to seek medical evaluation to determine the cause and appropriate treatment.To book online select the date and time that suits you best – alternatively, please contact us with any questions via the chat, call or email links provided.Address: 27 Welbeck Street, London, W1G 8ENTelephone: 020 7101 3377 Book Lymph Node Ultrasound

Thyroid Nodules: Symptoms, Causes, Diagnosis, & Treatment Thyroid nodules are growths or lumps in the thyroid gland, located in the front part of the neck. These nodules can be solid or fluid-filled and vary in size. While the presence of thyroid nodules can be concerning, the majority are benign (non-cancerous). However, a small percentage of thyroid nodules may be malignant (cancerous), making evaluation and monitoring important. Book Thyroid & Neck Ultrasound Causes of Thyroid NodulesThyroid nodules can result from several conditions, including:- Iodine Deficiency: Less common in areas where iodine is added to salt.- Overgrowth of Normal Thyroid Tissue: The reason for this overgrowth is often unknown, and it may not always require treatment.- Thyroid Cysts: Fluid-filled nodules resulting from the degeneration of thyroid adenomas.- Thyroiditis: Inflammation of the thyroid gland can lead to nodule formation.- Thyroid Adenomas: Benign tumors of the thyroid gland.- Thyroid Cancer: While most thyroid nodules are benign, a small percentage are cancerous.- Goiter: General enlargement of the thyroid gland can sometimes include the formation of nodules.SymptomsMany thyroid nodules do not cause symptoms and are often discovered incidentally during a physical examination or imaging studies performed for another reason. When symptoms do occur, they may include:- Visible swelling at the base of your neck- A palpable lump at the front of your neck- Difficulty swallowing or breathing if the nodule is large enough to press on your esophagus or windpipe- Thyroid gland dysfunction symptoms, such as unexplained weight loss or gain, changes in heart rate, and alterations in energy levels, depending on whether the nodule is producing thyroid hormonesDiagnosisThe evaluation of thyroid nodules typically involves:- Medical History and Physical Examination: Assessing symptoms and performing a neck examination.- Blood Tests: Measuring levels of thyroid hormones and thyroid-stimulating hormone (TSH) to assess thyroid function.- Ultrasound: Provides detailed images of the thyroid gland and nodules, helping to determine if a nodule is solid or fluid-filled and if there are characteristics suggestive of malignancy.- Fine-Needle Aspiration Biopsy (FNA): Involves extracting cells from the nodule with a thin needle for microscopic examination. This is the most reliable way to determine if a nodule is benign or malignant.- Thyroid Scan: In some cases, a radioactive iodine scan may be performed to assess whether the nodule is hot (producing too much thyroid hormone) or cold (not producing hormones).TreatmentTreatment options depend on the nature of the nodule:- Benign Nodules: May not require any treatment, but regular monitoring with ultrasound to check for changes in size or appearance.- Hyperfunctioning Thyroid Nodules: May be treated with radioactive iodine to shrink the nodule or with surgery.- Suspicious or Malignant Nodules: Surgical removal of part or all of the thyroid gland may be recommended. If thyroid cancer is confirmed, additional treatment, such as radioactive iodine therapy, may be needed.- Symptomatic Nodules: Even if benign, nodules causing symptoms due to their size or location may require surgical removal.Monitoring and Follow-UpRegular follow-up with a healthcare provider is crucial for monitoring the growth and any changes in thyroid nodules. This often includes periodic ultrasound examinations and, if necessary, repeat FNA biopsies. Book Thyroid & Neck Ultrasound Understanding thyroid nodules is key to effective management and ensuring that any potential issues are addressed promptly. For individuals with thyroid nodules, working closely with healthcare providers to monitor the condition and decide on the appropriate course of action is important.To book online select the date and time that suits you best – alternatively, please contact us with any questions via the chat, call or email links provided.Address: 27 Welbeck Street, London, W1G 8ENTelephone: 020 7101 3377 Book Thyroid & Neck Ultrasound

Thyroid tumours - Symptoms and causes Thyroid tumors can be either benign (non-cancerous) or malignant (cancerous), with the majority being benign. They arise from different cell types within the thyroid gland, leading to various types of tumors with distinct characteristics and treatment approaches. Understanding these tumors is crucial for appropriate diagnosis, treatment, and management. Book Thyroid & Neck Ultrasound Types of Thyroid Tumors- Benign Thyroid Tumors- Thyroid adenomas: These are the most common benign thyroid tumors, presenting as nodules within the gland. They typically do not cause symptoms and do not spread beyond the thyroid gland.- Malignant Thyroid Tumors (Thyroid Cancer)- Papillary thyroid cancer: The most common type of thyroid cancer, accounting for about 80% of cases. It grows slowly and is usually curable, especially if diagnosed early.- Follicular thyroid cancer: Makes up about 10-15% of thyroid cancer cases. It's more likely to spread to the blood vessels and distant organs compared to papillary cancer but still has a good prognosis.- Medullary thyroid cancer: Accounts for 3-4% of thyroid cancers. It originates from C cells that produce calcitonin, a hormone. It can be sporadic or part of genetic syndromes like Multiple Endocrine Neoplasia type 2 (MEN2).- Anaplastic thyroid cancer: A rare, aggressive form of thyroid cancer that is difficult to treat. It typically occurs in older adults.- A palpable nodule or lump in the neck- Changes in voice, including hoarseness- Difficulty swallowing or breathing- Swollen lymph nodes in the neck- Pain in the thyroid region or neck- Physical examination: To check for nodules or swelling in the thyroid gland.- Blood tests: Assessing thyroid function and, for medullary thyroid cancer, measuring calcitonin levels.- Ultrasound: To evaluate the characteristics of thyroid nodules.- Fine-needle aspiration biopsy (FNAB): The removal of thyroid tissue for microscopic examination, which is crucial for determining if a tumor is benign or malignant.- Genetic testing: Particularly for medullary thyroid cancer, to identify hereditary conditions.- Benign tumors often require monitoring without immediate treatment. Surgery may be recommended if the tumor causes symptoms or cosmetic concerns.- Papillary and follicular thyroid cancers are typically treated with surgery to remove part or all of the thyroid gland, possibly followed by radioactive iodine therapy to eliminate any remaining cancer cells.- Medullary thyroid cancer treatment includes surgery, and patients may also benefit from genetic counseling.- Anaplastic thyroid cancer may require a combination of surgery, radiation therapy, and chemotherapy, although the prognosis remains challenging. Book Thyroid & Neck Ultrasound Follow-up and PrognosisRegular follow-up care is important for anyone diagnosed with a thyroid tumor to monitor for recurrence, especially for thyroid cancers. The prognosis for thyroid cancer is generally favorable, with high survival rates for papillary and follicular cancers. Early detection and treatment significantly improve outcomes, underscoring the importance of monitoring thyroid health and addressing any changes promptly.To book online select the date and time that suits you best – alternatively, please contact us with any questions via the chat, call or email links provided.Address: 27 Welbeck Street, London, W1G 8ENTelephone: 020 7101 3377 Book Thyroid & Neck Ultrasound

Abnormal thyroid hormone blood result Abnormal thyroid hormone blood test results can indicate an imbalance in the body's thyroid function, potentially signifying hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid), among other thyroid conditions. Understanding these results and their implications is crucial for diagnosis and management. Here’s a breakdown of the primary thyroid function tests and what abnormal results might indicate: Book Thyroid & Neck Ultrasound Thyroid Function Tests- Thyroid Stimulating Hormone (TSH): Produced by the pituitary gland, TSH stimulates the thyroid to produce thyroid hormones. It's often the initial test for thyroid function.- High TSH: Typically indicates hypothyroidism, as the pituitary releases more TSH to stimulate an underactive thyroid.- Low TSH: Suggests hyperthyroidism, where excessive thyroid hormone production suppresses TSH release.- Free Thyroxine (FT4): Measures the free, or unbound, T4 hormone available to the body's tissues.- High FT4: Can indicate hyperthyroidism.- Low FT4: Usually signifies hypothyroidism.- Free Triiodothyronine (FT3): Though not always measured, FT3 can provide additional information, as T3 is the active form of thyroid hormone.- High FT3: Often seen in hyperthyroidism.- Low FT3: Less commonly used for diagnosing hypothyroidism, but low levels can still reflect reduced thyroid function.- Hypothyroidism: Characterized by high TSH and low FT4 levels. Symptoms might include fatigue, weight gain, cold intolerance, and dry skin.- Hyperthyroidism: Indicated by low TSH and high FT4 (and possibly high FT3) levels. Symptoms can include weight loss, anxiety, increased heart rate, and heat intolerance.- Subclinical Hypothyroidism: Elevated TSH levels with normal FT4 levels. Individuals may or may not exhibit symptoms.- Subclinical Hyperthyroidism: Low TSH with normal FT4 and FT3 levels. Often asymptomatic or with mild symptoms.- Hypothyroidism causes include Hashimoto's thyroiditis, thyroid surgery, and certain medications.- Hyperthyroidism causes include Graves' disease, toxic adenomas, and subacute thyroiditis.- Antibody tests: To detect autoimmune thyroid diseases like Hashimoto's thyroiditis and Graves' disease.- Ultrasound: To examine the thyroid's structure and look for nodules.- Radioactive iodine uptake test: To assess how well the thyroid gland takes up iodine, which can help differentiate causes of hyperthyroidism. Book Thyroid & Neck Ultrasound Treatment- Hypothyroidism is typically treated with synthetic thyroxine (T4), adjusting the dose based on TSH levels and clinical response.- Hyperthyroidism treatment options include antithyroid medications, radioactive iodine ablation, or thyroidectomy, depending on the cause, severity, and the patient’s overall health.Abnormal thyroid hormone levels require careful evaluation by a healthcare provider, who can offer a diagnosis and create a personalized treatment plan. Managing thyroid conditions effectively often involves ongoing monitoring and adjustment of treatment to maintain optimal thyroid hormone levels and improve quality of life.To book online select the date and time that suits you best – alternatively, please contact us with any questions via the chat, call or email links provided.Address: 27 Welbeck Street, London, W1G 8ENTelephone: 020 7101 3377 Book Thyroid & Neck Ultrasound
