Invasive lobular carcinoma.
About 10% – 15% of invasive breast cancers are
invasive lobular carcinomas. This invasive cancer starts in the lobules and spreads
into the fatty tissues of the breast (Figure 6). Like invasive ductal carcinoma, this
cancer can then spread beyond the breast to other parts of the body.
Mixed tumors.
Mixed tumors contain a variety of cell types, such as invasive ductal
carcinoma combined with invasive lobular carcinoma. Mixed tumors are usually
treated as an invasive ductal cancer.
Inflammatory breast cancer.
About 1% – 3% of all breast cancers
are inflammatory breast cancer. This
cancer is sometimes called by its
abbreviation—IBC. In this disease,
cancer cells have spread to the lymph
node channels in the skin of the breast.
The skin of the diseased breast is red,
feels warm, and has the look of an
orange peel (Figure 7). The diseased
breast may also become larger,
firmer, tender, or itchy. Inflammatory
breast cancer is often mistaken for an
infection in its early stages. It has a
higher chance of spreading and worse
prognosis than common invasive ductal
or invasive lobular carcinomas.
