What cancer treatment took, and whether it comes back: hair, hearing, fertility, bone, muscle, nerves, memory, the heart, skin, sexual function and the years afterwards. Recovery begins during treatment rather than after it, and structured exercise has more evidence behind it than everything sold as rejuvenation put together.
Supportive care keeps a person well enough to get through treatment. It handles the sickness, the pain, the sore mouth and the low blood counts while treatment is happening, and when treatment stops, most of it stops too. This front asks the other question, the one that starts on the last day: what did the treatment take, and does it come back? Hair and eyebrows, hearing, fertility, bone, muscle, the nerves in the hands and feet, memory and concentration, the heart, skin and scars, sexual function, sleep, work, money, the people who were caring for you, and the body's measured biological age. That is the line. Where a measure sits on both sides of it, the record is shared with supportive care rather than written twice.
The honest one-line summary of the evidence is that exercise outperforms everything sold as rejuvenation, and it is not close. In the CHALLENGE trial, 889 people with resected colon cancer were randomised after adjuvant chemotherapy to a three-year coached exercise programme or to health-education materials; at a median follow-up of 7.9 years, disease-free survival was longer with exercise (hazard ratio 0.72, 95% CI 0.55 to 0.94), five-year disease-free survival was 80.3 against 73.9 per cent, and eight-year overall survival was 90.3 against 83.2 per cent. For fatigue, a meta-analysis of 113 studies and 11,525 participants put exercise at a weighted effect size of 0.30 and psychological therapy at 0.27, against 0.09 for drugs, which did not reach significance. No supplement, infusion, peptide or clinic programme sold for recovery has produced a result of that kind in any cancer, and most have produced no randomised result at all.
