Thanks for writing.
All tender spots or breast pain
DO NOT indicate cancer.
Moreover your last mammogram
which was done few months back was normal.
After 50 years of age, yearly mammograms are recommended.Breast cancer
is diagnosed with physician and self examination of the breasts for lumps , mammography
testing and biopsy of any lump felt.
You do not have any lump. Besides the tenderness you have in an area of your breast could be due to trauma sustained while working which has gone unnoticed by you.
Lack of proper breast support can further lead to dull aching pain in the breast if they are heavy.
The risk of breast cancer is higher if you have relatives(sister, mother or daughter) with the disease. Alcohol, obesity further increase the risk.
Past history of Mastitis DOES NOT increase the risk of breast cancer. Also breast feeding and having children is protective for breast cancer.
I hope I have answered your query.
