What is Colon Melanoma?
Colon melanoma is an extremely rare form of melanoma, a type of cancer that usually occurs in the skin. When melanoma develops in the colon, it is typically the result of metastasis from a primary melanoma elsewhere in the body, as primary melanoma of the colon is exceedingly rare. Melanoma is known for its ability to spread to other parts of the body, including the gastrointestinal tract.
Symptoms
Symptoms of colon melanoma can be similar to other types of colorectal cancers and may include:
- Changes in bowel habits, such as diarrhea or constipation.
- Presence of blood in the stool or rectal bleeding.
- Abdominal pain or discomfort.
- Unexplained weight loss.
- Fatigue and weakness.
- In cases where the colon melanoma is a metastasis, symptoms of primary melanoma or other metastatic sites may also be present.
Disease Aetiology (Causes)
Colon melanoma most often occurs due to the metastasis of a primary melanoma located elsewhere in the body. Factors that increase the risk of primary melanoma include excessive sun exposure, having fair skin, a history of sunburn, and a family history of melanoma. The exact mechanism by which melanoma spreads to the colon is not fully understood but involves the dissemination of melanoma cells through the body’s lymphatic or blood systems.
Diagnosis
Diagnosing colon melanoma involves:
- Colonoscopy: To visually inspect the colon and obtain tissue samples.
- Imaging Studies: Such as CT scans, MRI, or PET scans, to identify the extent of the cancer and check for other metastatic sites.
- Biopsy: A tissue sample from the colon is examined under a microscope. The presence of melanin or specific markers can indicate melanoma.
- Skin Examination: To check for primary melanoma sites.
Treatment
Treatment for colon melanoma depends on whether it is a primary tumour or a metastasis:
- Surgery: To remove the tumour in the colon, often along with surrounding lymph nodes.
- Chemotherapy and Immunotherapy: Used to treat melanoma, particularly if it has spread.
- Targeted Therapy: For tumours with specific genetic mutations.
- Radiation Therapy: May be used for symptom control or in specific situations.
What support can we give for the Colon Melanoma?
Colon Melanoma is a rare cancer, meaning it is not as well-known as other forms of cancer. Without a Ribbon is an Australian organisation that provides support for individuals who suffer from rare cancers. So, we provide a designated platform for Warriors to obtain information specific to their Rare Cancer. We also provide annual opportunities for our Warriors to meet and learn from each other. If you suffer from rare cancer such as Colon Melanoma, we can help and support you through your journey thanks to the generous donations we receive.
