Breast Cancer

Cáncer de mama

What it means

Breast cancer is a cancer that starts in breast tissue. It happens when cells in the breast change and grow out of control, and the extra cells can form a mass called a tumor. The National Cancer Institute dictionary says the most common type is ductal carcinoma, which begins in the lining of the milk ducts; another type, lobular carcinoma, begins in the lobules (milk glands). Cancer that does not spread any further is called "in situ," and cancer that spreads outside the breast is called "invasive." Breast cancer occurs in both men and women, although male breast cancer is rare. Tools used to diagnose it include a physical exam, imaging tests such as a mammogram, and a breast biopsy. In Spanish the term is cáncer de mama.

Cáncer de mama is masculine: el cáncer de mama. It is the term defined in the National Cancer Institute's Spanish dictionary, which adds that it is also called cáncer de seno and cáncer mamario. MedlinePlus en español titles its health topic Cáncer de seno, lists cáncer de mama and cáncer de pecho as other names, and uses both mama and seno for the breast in the same text. The adjective is mamario, as in tejido mamario (breast tissue).

The two types named in the definition are carcinoma ductal and carcinoma lobulillar; the MedlinePlus en español encyclopedia writes carcinoma lobular. The milk ducts are los conductos, the lobules los lobulillos, and the nipple el pezón. MedlinePlus en español keeps the Latin "in situ" and gives invasive as invasivo. Words that come up at appointments include bulto (lump), axila (armpit), mamografía (mammogram) and biopsia de mama (breast biopsy).

Your right to an interpreter in the United States

If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.

You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
