I had a VATS (Video assisted thorocadamy, sp?) lobectomy. No massive muscle cuts, just four incisions. Still pretty sore, but thats to be expected.
I agree, its early to tell, some is definatly surgical weakness, and I was told the other two lobes tend to expand some. In theory its about a 20% reduction, in practice the surgeon says it tests closer to 10. That in general is for an older and less healthy population.
My ride was nothing earth shattering for sure. Just 6 miles of flat slowish riding. I didnt feel to bad after, I seem to be getting decent at this recoverying after surgery or chemo thing, a dubious skill at best. lol.
