Which cancer primarily affects women and has a significant public awareness campaign associated with it?

Breast cancer is the cancer that primarily affects women and is associated with a significant public awareness campaign. This awareness is critical given that breast cancer is one of the most common cancers among women worldwide. The campaigns often focus on education about risk factors, the importance of early detection through screenings like mammograms, and the promotion of self-examinations. High-profile events such as Breast Cancer Awareness Month, marked by the pink ribbon symbol, further emphasize the widespread focus on breast cancer education and prevention efforts.

The other cancers listed do not have the same level of public awareness or major campaigns associated with them. While uterine and ovarian cancers also primarily affect women, the recognition, education, and community outreach surrounding breast cancer are far more extensive. Skin cancer is more common overall but does not primarily affect women, making breast cancer the most relevant answer in this context.
