Hi, this is my first post!

My mother (Bala Saigal, aged 55) has been diagnosed with an oral cancer.

She had an ulcer in left base of tongue for which the biopsy report says Invasive well differentiated keratinizing squamous cell carcinoma... this ulcer was removed by a small surgery and it has healed quite effectively.

Besides, she also underwent a few other tests including CT Scan for neck & blood tests. The CT Scan refutes the presence of any significantly enlarged cervical lymph node and the blood tests are also clear.

The surgeon also used palpation before to find out any indication for the enlarged cervical lymph node and he didn't find any.

From the above mentioned, facts - can the stage of the cancer be ascertained? Besides, how good is the radiation therapy after the ulcer has been removed surgically? Also, how good are the cures for oral cancers these days?

I'm looking forward to your quick response(s) as we are under tremendous pressure & tension..
