Thanks for a great blog Marcella - it is very inspiring. You are a credit to us all. I am feeling a good benefit from my use of anti-depressants - something to think about if you need to talk to your doctor about it.
I presume your type of cancer (head neck cancer) - is a squamous cell carcinoma (these are the type of cells which are prevalent in that area.
It is well known that these cells are very susceptible to radiotherapy treatment. Indeed some people have RT as their only treatment (Actor Michael Douglas had throat cancer - successfully treated by RT).
Some people have a combination of both chemo and RT.
These treatments (tho tough to contend with) are clinically proven to be successful in the treatment of head/neck cancers.
Don't discount them Marcella - just make sure you get the advice of your medical team first.
kind regards tony k
