Final answer:
C) Breast cancer is the most common type of non-skin cancer in females and can generally be treated effectively if detected early.
Step-by-step explanation:
The most common type of non-skin cancer in females is breast cancer. Excluding skin cancers like basal cell carcinoma, breast cancer is exceedingly prevalent among women and accounts for a significant portion of cancer cases. This disease leads to abnormal growth of cells within the breast, forming a tumor which may be detected through different screening practices like mammograms. Although breast cancer is rare in teenagers, the risk increases with age, and early detection is crucial since it can usually be cured with surgery when found early.
