I, for one, found out the hard way that 1 or 2 cigarettes a day were 1 or 2 too many. Started off as 1 a week and 6 months later, it was 1 a day. Four years later if was loss of voice box and total largectomy.

So soon after treatment, he is just asking for a reoccurrence. The tissues are still so sensitive. He need to stop now. Try to avoid stressful situations. Get some help from social worker at hospital. But if he is also cancelling dr appointments he sounds like he is in denial and needs more help than just quitting. Sounds like he is depressed. It is common after dx of cancer and nees to be addressed. Your friend should probably also seek medical help. Sounds like her stress levels have reached an unmanagable proportions without help. Its is not just the patient that is affected by thsi but the entire faimly.

Take care,
Eileen
