Non-hereditary breast cancer under 40... statistics

The chances of this being anything is slim!

It's not none though, so that's why it's good you're following up.

I will say that I was in a similar boat. Grandmother survived BC, mother died from it, I have no known mutations, and the doctor found a lump at 38. For me, it did turn out to be cancer. It's been, and continues to be, a huge pain in the butt. But it hasn't actually been a catastrophe. I am getting through, and, if you need to, so will you.

The waiting time is very hard. Distract yourself or absorb yourself in whatever works for you. Ask for an rx for valium or Ativan from your doc if you really need it. You can do this!

Here you go, 3 different ways to look at it.

First is the percent risk over 10 years for each decade of life. In other words, over the entire 10 years of one's 30s, the risk is less than 1/2 a percent.

Second is the number of cases diagnosed each year per 100,000 women, by age. For those aged 30-34, it looks like about 50 cases per 100k; for those aged 35-39, it looks like about 65-70 cases per 100k.

Third is the likelihood of being diagnosed with breast cancer at various ages. Over our entire lifetime, the risk is 1 in 8. But by the age of 40, the risk is only 1 in 217.

Edited to add: djmammo and I were posting at the same time.

I agree with Illimae. Don't let anyone EVER discount you because of your age or your lack of genetic mutations.

I was 41 at dx. Mother had BC in her 60s. I do not have any mutations either. Yet here I am.

Hoping that your results will come back fibrocystic or benign.

Hang in there.
