Breast and lung cancer are the leading causes of cancer deaths in women.

1. Breast Cancer: This is the most common cancer among women worldwide. It occurs when some breast cells begin to grow abnormally. These cells divide more rapidly than healthy cells and continue to accumulate, forming a lump or mass.

2. Lung Cancer: This is the leading cause of cancer deaths in women in several countries. It's primarily caused by smoking, though non-smokers can also develop lung cancer. It occurs when cells in the lungs mutate or change. Various factors such as exposure to radon gas, asbestos, and air pollution can also contribute to the likelihood of developing lung cancer.

While ovarian and colon cancers are also common in women, they do not cause as many deaths as breast and lung cancer. However, early detection and treatment can significantly improve the prognosis for these cancers.
