D07: Carcinoma in situ of other and unspecified genital organs

The term "Carcinoma in situ of other and unspecified genital organs" refers to a group of conditions where abnormal cells are found in the genital organs but have not spread to nearby tissues. This type of cancer is considered an early stage, as the cancer cells are localized and limited to the layer of tissue where they began. The genital organs can include the vagina, vulva, penis, testicles, or scrotum. These conditions are not transmitted from person to person but are typically caused by changes in DNA within cells. Symptoms can differ based on the organ affected but may include discomfort in those areas, skin changes, lumps, or unusual discharge. As the disease progresses, if untreated, these abnormal cells can develop into invasive cancer and affect surrounding tissues and potentially other parts of the body.
