A TB patient can live a long and healthy life with proper treatment. The median survival time after successful treatment is 10.5 years, and the survival probability for 11 years after successful treatment is 70%. However, certain factors can influence longevity, such as previous TB treatment, high age, kidney failure, and cancer.
While TB can be a serious illness, it's important to remember that with effective treatment, the vast majority of people can recover and live long and healthy lives.
