What is Cancer?
Cancer is a broad term for a collection of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These cells can invade and destroy normal tissue, and have the potential to spread to other parts of the body through the blood and lymph systems.
How Does Cancer Develop?
Cancer develops when genetic mutations occur in a cell's DNA. These mutations can be caused by various factors, including exposure to carcinogens, lifestyle factors such as smoking, and genetic predisposition. The mutations disrupt normal cell growth and division, leading to the formation of a mass of abnormal cells, known as a tumor.
Can Cancer be Prevented?
While not all cancers can be prevented, there are steps that can reduce the risk of developing cancer. These include:
Avoiding tobacco use
Maintaining a healthy diet
Engaging in regular physical activity
Limiting alcohol consumption
Protecting skin from excessive sun exposure
Getting vaccinated against certain infections
Undergoing regular screening and early detection tests
What is the Prognosis for Cancer Patients?
The prognosis for cancer patients varies widely based on the type and stage of cancer, as well as individual factors such as age and overall health. Advances in cancer treatment have improved survival rates for many types of cancer, and early detection remains a key factor in improving outcomes.
