Web12. Cancer is the result of an improperly regulated cell cycle. Describe two reasons why cells can form tumors. Cells can form tumors due to the mutations within the tumor suppressor genes or the proto-oncogenes this leading to tumors within an organism, or the result of cancer which occurs due to the result of improperly regulated cell cycles. WebDec 23, 2024 · Chemo works by halting cancer cell division, often by interfering with RNA or DNA synthesis, and shrinking the tumor.

"WebTumor suppressor genes are normal genes that slow down cell division or tell cells to die at the right time (a process known as apoptosis or programmed cell death). When tumor suppressor genes don't work properly, cells can grow out of control, which can lead to cancer. A tumor suppressor gene is like the brake pedal on a car.
