What does hormone therapy do in relation to cancer cells?

Hormone therapy plays a vital role in the treatment of certain types of cancer, particularly those that are hormone-sensitive, such as breast and prostate cancers. Its primary function is to interfere with the growth of cancer cells by targeting proteins that are necessary for the proliferation of these cells. This may involve blocking the body's natural hormones or interfering with their effects on cancer cells, thereby preventing them from receiving the signals they need to grow and multiply.

By specifically focusing on the hormonal pathways that fuel the growth of cancer, hormone therapy can effectively limit the growth of tumors, reduce their size, and help manage the overall progression of the disease. This targeted approach makes it a valuable option in a comprehensive cancer treatment plan, especially when cancer cells are reliant on hormones for survival and proliferation.

The other options do not accurately reflect the purpose or function of hormone therapy in the context of cancer. Promoting the growth of cancer cells, enhancing cell mitosis for recovery, or stimulating cell reproduction would not be effective approaches in cancer treatment, as the goal is to actively hinder cancer cell growth instead.
