Every woman I know who has known a man with breast cancer has told me he's dead

A mammogram is an X-ray of the chest. Usually the side view is the most helpful and relevant. They have specialized machines where you put a boob in each cavity and your done a few minutes later without needing to appear topless in front of anyone.

As for squeezing a man's pectorals... Squeezing doesn't hurt, at least not more than any other body part and provided the pecs are muscular or at least tight.

I think if it hurts, you're probably not doing it right. Try to do more of a massage than a pinch/squeeze. If there's a hard lump you'll still be able to feel it without being too rough.

A mammogram is an x-ray test that produces an image of the inner breast tissue on film. This technique, called mammography, is used to visualize normal and abnormal structures within the breasts. Mammography, therefore, can help in identifying cysts, calcifications, and tumors within the breast. It is currently the most effective way to detect early breast cancer. Breast self- examination (BSE) on a monthly basis and examination by a doctor are still important, but physical examinations typically find breast cancers when they are much larger than those detected by mammography. While mammography can discover a small cancer in a curable stage it not foolproof. Ten to fifteen percent of breast cancers are not identified by mammography and these cancers are found by physical examination.
