Cancers that affect epithelial tissues are called a. leukemias b. lymphomas c. sarcomas

none of them. the answer is carcinomas

Carcinoma is a category of types of cancer that develop from epithelial cells. Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal or ectodermal germ layer during embryogenesis. (defenition from wikipedia and answer from my brain :) )

I am afraid none of the options correspond to what you're looking for. Take a look:

Leukemias: cancer that affects bone marrows.

Lymphomas: cancer that affects lymphocytes (immunity system cells)

Sarcomas: cancer that affects connective and non-epithelial tissue.

There are either 2 options. The question was either typed incorrectly, and you're looking for a cancer type that doesn't affect epithelial tissues (which would be a sarcoma) or you forgot to add one option, which would be:

Carcinomas. Carcinomas are a type of cancer that attacks epithelial tissues, which are found all over the body, which explains why these make up about 90 percent of all cancer cases.
