When the repair system in the body malfunctions and fails to detect and repair damaged cells, cancer cells can grow unchecked. This unchecked growth can lead to the formation of tumors and the spread of cancer to other parts of the body. Without the body's repair system functioning properly, there is nothing to stop the rapid proliferation of cancer cells, leading to the progression of the disease. **

This unchecked growth can result in the formation of tumors, which can invade surrounding tissues and spread to other parts of the body, a process known as metastasis. Without the repair system to detect and repair DNA damage or eliminate abnormal cells, the cancer cells can continue to divide and grow, potentially leading to serious health consequences and even death. **
