Invasive ductal carcinoma is the most common form of invasive breast cancer, accounting for 40%-75% of the incidence of breast cancer upon diagnosis. Invasive ductal carcinomas designated as "no special type" are the most common type of these tumors.

Invasive lobular carcinoma is the second major biologically distinct type of invasive breast cancer behind invasive ductal carcinoma, constituting 5%-15% of all invasive cases of breast cancer. It usually affects older women.

Invasive papillary carcinoma is a very rare subtype of breast carcinoma that affects mostly postmenopausal women. It has a better prognosis than classic invasive ductal carcinoma.

Tubular carcinoma is a rare, well-differentiated, distinct type of breast cancer with an excellent prognosis. It is more common in elderly women and is less likely to have lymph node metastasis vs classic invasive ductal carcinoma.
