For example, someone with cancer can undergo surgery, chemotherapy, and radiation therapy; but these may come with chronic pain, cognitive problems, kidneys, heart, joints, or even more cancers.
Even treatments for simple diseases such as an infection, is usually treated with antibiotics, and can cause hearing loss, tinnitus, and balance problems.
