D03.4: Melanoma in situ of scalp and neck
The tissue in the body is made up of cells. Cancer causes the cells to change, resulting in them multiplying uncontrollably. This leads to a malignant neoplasm (abnormal growth of tissue) developing. This abnormal and excessive tissue growth is called cancer. In your case, the cancer is limited to the skin. This means that the cancer is very superficial and has not currently extended beyond a certain limit in the tissue. This also means the cancer has not yet been able to spread to other organs. However, the cancer cells can destroy the healthy tissue.
You often don’t get any symptoms with this early form of cancer. Melanoma is often visible as dark spots on the skin. This form of skin cancer is made up of certain skin cells that have a dark pigment in them.
