Which type of cancer is 5-fluorouracil (5-FU) commonly used to treat?

• A. Breast Cancer
• B. Prostate Cancer
• C. Lung Cancer
• D. Colorectal Cancer

Answer: (D)

5-fluorouracil (5-FU) is commonly used in the treatment of colorectal cancer due to its mechanism of action and effectiveness in targeting the rapid cell division characteristic of this type of cancer. 5-FU is an antimetabolite that interferes with DNA and RNA synthesis by mimicking uracil, thereby disrupting the cancer cell's ability to proliferate. In the context of colorectal cancer, numerous clinical trials and treatment protocols have established 5-FU's role in both adjuvant and palliative settings, often in combination with other chemotherapeutic agents. The drug works particularly well with the cancer-specific pathways involved in the growth of colorectal tumors. While 5-FU may also be used in the treatment of other cancers, such as breast cancer, it is particularly recognized for its efficacy in colorectal cancer, which is why it is primarily associated with this indication in medical practice and literature.
