What is the most common type of breast cancer?

Invasive ductal carcinoma is indeed the most common type of breast cancer, accounting for a significant majority of breast cancer cases. This form of cancer originates in the milk ducts and then invades surrounding breast tissue, which allows it to spread to lymph nodes and other parts of the body if not treated early.

The prevalence of invasive ductal carcinoma can be attributed to various factors, including its biological characteristics, which tend to manifest early and aggressively in many individuals. The diagnosis often occurs through routine mammography or self-examination when a lump is discovered, leading to a relatively high incidence rate.

While invasive lobular carcinoma, DCIS, and mucinous carcinoma are also types of breast cancer, they occur less frequently. Invasive lobular carcinoma, for instance, makes up a smaller percentage of breast cancers and has differing growth patterns and characteristics. DCIS is a non-invasive condition that typically describes cancerous cells confined within the ducts, and although it is a precursor to invasive cancer, it is not considered invasive by itself. Mucinous carcinoma, on the other hand, is rare and characterized by the production of mucin, which affects its incidence and presentation.
