What is the reason for feeling i guess vessels in my left and right breast in the same position? i do not have any children.

Breast "feeling": Breast "feeling" composition is 'tricky" as there are milk ducts, fat, fibrous tissue and sometimes nodules. I can't answer whether those are vessels or not without a physical exam, but you should see a MD and get an accurate breast exam done if you are unsure. Breast cancer knows no age limit.

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor for an evaluation.
