I already had all the mamms I plan to have in this life. In my 40's I had a lump and got run through the cancer system. Now that I know how it works, I see no point. Especially if you have no lumps. If you have a lump, Step 1 is to have someone else check it for you. Step 2 is ultrasound or thermography. Mammograms aren't sensitive or specific enough to be worth the radiation exposure, they are simply a replacement for a woman touching her own breasts. If you are familiar with your boobs, you're way ahead of the detection that modern medicine has slated for you.
