"CANCER".... the filthiest, most horrible word in our language.
As the survivor (so far) of a number of cancers and surgeries for same, I extend my deepest sympathies.
It's a helpless feeling, watching the onslaught of this horrid condition, and being utterly unable to do anything except offer moral support. All the same, it often seems that the patient truly appreciates the support and, at last mentally, is reinforced in his or her determination to fight it out.
I hope that this applies here and now.
