According to the Science Direct website: “Thyroid disease is a highly prevalent condition with impact on childhood development, women’s fertility, and risk of malignancy, making it an important global health issue of high priority.”
“Many South Africans are still unaware of what the thyroid is and what to look out for when it comes to thyroid health,” says Dr Justus Apffelstaedt, a specialist surgeon with an interest in thyroid and parathyroid health management. “Being armed with the facts greatly increases the opportunity for early detection and diagnosis, which are a patient’s best chance for recovery.”
While thyroid dysfunction is fairly common, diseases of the thyroid such as hypothyroidism (lack of thyroid hormones secreted) and hyperthyroidism (increase in thyroid hormones secreted) are rarely cancerous and can usually be well-managed.
“Thyroid cancer has a low incidence within the general population,” says Dr Fatima Hoosain, a specialist surgeon. “But it is still one of the more common cancers. Fortunately, with early detection, there is a high survival rate. Like many cancers, thyroid cancer can have a genetic component. People with a family history of thyroid cancer or the rare pheochromocytoma tumour (a tumour that develops in the adrenal gland that is usually benign), have higher chances of developing thyroid cancer. As in the case of breast cancer, a genetic test can be advised to determine if the patient carries genes that increase the potential risk of having the disease.”
A key factor in early thyroid disease diagnosis is that doctors must not ignore patients who present early symptoms. Whilst symptoms do vary, some can be fairly generic and include:
- The appearance of a lump in the neck
- Swollen lymph nodes
- A persistent cough not linked to a cold
- Difficulty in breathing
- Constant voice changes and hoarseness
The abovementioned signs and symptoms most commonly point to benign causes but can be related to thyroid cancer; so if they are present, medical advice is recommended.
“These days, many patients undergo imaging such as CTs, MRIs, and ultrasounds of the neck for problems unrelated to the thyroid,” says Dr Apffelstaedt. “Often, in these examinations, there is an incidental finding of a lump in the thyroid gland. The vast majority of these lumps are benign, but they must be further investigated to avoid missing a cancer. This is done with ultrasound by a skilled operator and, in some cases, taking a sample of the lump with a fine needle for examination by a pathologist. These procedures are generally enough for a diagnosis. An operation to remove part of the thyroid gland where the lump resides is sometimes done for a final diagnosis, but this is rarely required.”
Surgery is generally the main treatment of thyroid cancer. If thyroid cancer is diagnosed by a fine needle biopsy, surgery to remove half or all of the thyroid gland is recommended. The slow growth of most thyroid cancers also means that if treated properly, they have an excellent prognosis. It is rare for thyroid cancers to require more aggressive treatments such as radiation, chemotherapy, and biologicals.
Dr Justus Apffelstaedt is a former Associate Professor of Surgery and Head: Surgical Oncology Service, University of Stellenbosch. Dr Justus Apffelstaedt earned a Medical Degree and a Doctorate in Medicine in Germany, as well as an MMed and FCS(SA) in South Africa and an MBA from Bond University in Australia.
He has represented developing countries on the Breast Surgery International (BSI) council and is a founding member and first chairman of the Breast Interest Group of Southern Africa (BIGOSA).
He is a fellow and life member of the International Union Against Cancer (UICC) Fellows.
He is excellent at translating complex medical terminology into easily understood language and is a proponent of proactive breast health management through extensive dissemination of information to the general public.
His breast service is the only one in Africa to publish peer-reviewed data comparable to international breast practices in breast screening. He is also the author and co-author of several publications in peer-reviewed national and international journals on breast cancer screening and breast health issues.
His current interest and field of practice includes breast health. thyroid, parathyroid, and soft tissue tumours.
He has practices in Cape Town, South Africa, and Windhoek in Namibia.
Dr Fatima Hoosain is a specialist surgeon who enjoys all aspects of General Surgery, with a particular interest in breast and thyroid health. This includes surgery for breast, thyroid and soft tissue tumours.
Dr Hoosain graduated with an MBChB from the University of Stellenbosch in 2009, subsequently specialised in General Surgery and qualified with an FCS (SA) and MMed (Surg) in 2019. She has been involved in the publication of several journal articles.
Dr Hoosain is also a member of the Breast Interest Group of South Africa (BIGOSA), the Association of Surgeons of South Africa (ASSA), the Surgical Research Society of South Africa (SRS) and the South African Colorectal Society.
