What is the most common type of cancer by occurrence for women in the US?

Breast cancer is the most common type of cancer diagnosed among women in the United States when considering occurrence rates. This classification is based on statistical data collected and reported by health organizations, which indicate that breast cancer surpasses other types of cancer in terms of the number of new diagnoses each year among the female population.

Breast cancer's prominence can be attributed to several factors, including genetic predisposition, lifestyle factors, and the increased effectiveness of screening practices like mammography that allow for earlier detection of cases. Although skin cancer is also common, particularly non-melanoma skin cancers, breast cancer accounts for a higher incidence rate specifically among women.

In contrast, lung cancer, while a significant health concern and leading cause of cancer-related death for women, does not have the same incidence rate as breast cancer. Similarly, colorectal cancer ranks lower in occurrence among female cancers. Thus, breast cancer clearly holds the position as the leading type of cancer diagnosed in women in the US.
