Are there any biochemical tests to confirm breast carcinoma apart from clinical examination..

No: Biochemical screens are of no value in this situation. If someone has told you otherwise, they are deceived or lying. If you have a suspicious mass, it needs to be biopsied. I hope things work out for you -- the vast majority of breast cancers caught early are cured nowadays.

Only way: To confirm breast cancer is by biopsy only , examination is for clinical diagnosis only , confirmation is by tissue examination ( pathology ) , biochemical tests , tumor markers is for monitoring purposes only.

Biopsy/Microscopic-E: Clinical exam is part of the diagnosis process. But final confirmation is done with a biopsy and microscopic examination. There are special tests done to further classify the type of breast cancer; these iclude er/pgr and her2 testing.
