Felt stiff on my right breast

I felt itchy on the line of brassiere, then I scratched. What's this? There were two stiff under my right breast which smaller than pachinko ball.

For a beat, flashing through my mind that the ward "breast cancer" .

I checked on the website it on my conscience. It seems that all stiff was not always true that breast caner, sometimes the stiff is made by hormone system.

One of the website said "more than 80% people who visit the hospital by stiff
will be benign, let's go to take the examination of breast cancer as soon as possible for clearing whether malignant or benign."

I'll be 30 this year, if there is examination of breast cancer of company's health checkup, I was going to take it. However I didn't know which month the health checkup is.

I'll try to take the examination. If it was noting I feel easy, if it was breast cancer it's better to find earlier. I made the decision to take the examination.

I told my husband about my stiff on my breast. He told me that it's better to take the examination. But he also think that I'll never made breast cancer.

Where can I take the examination?
