| N-SC lung cancer stage | ||
|---|---|---|
| Chemo alone | 1\% | 18\% |
| Chemo plus radiotherapy without surgery | 6\% | 35\% |
| Total | 24\% | 60\% |
Do chemotherapy drugs really work?
The good news is that most normal cells will recover from the effects of chemo over time. But cancer cells are mutated (not normal) cells, and they usually do not recover from the effects of chemo. This is why chemo is good at killing many types of cancer cells.
Does chemo shorten life expectancy?
During the 3 decades, the proportion of survivors treated with chemotherapy alone increased from 18\% in 1970-1979 to 54\% in 1990-1999, and the life expectancy gap in this chemotherapy-alone group decreased from 11.0 years (95\% UI, 9.0-13.1 years) to 6.0 years (95\% UI, 4.5-7.6 years).
How long do chemotherapy drugs stay in your system?

What percentage of people survive cancer?

What is the survival rate of chemotherapy?
The overall contribution of chemotherapy to 5-year survival was found to be just 2.1\% for cancer patients in the U.S. and 2.3\% for patients in Australia.
How many people die from chemo?
RESULTS. There were 44 patients (27\%) who died while receiving their first line of chemotherapy, 39 (24\%) patients died after two lines of chemotherapy treatment and 72 patients (45\%) were on third line, or subsequent lines of treatment ( Table 4 ). In six cases (4\%), the line of therapy was not documented.
How effective is chemotherapy?
It works by keeping the cancer cells from growing and dividing to make more cells. Because cancer cells usually grow and divide faster than normal cells, chemotherapy has a greater effect on cancer cells. However, the drugs used for chemotherapy are powerful, and they can still cause damage to healthy cells.
