Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells.
What are the common risk factors for developing cancer?
Some common risk factors for developing cancer include tobacco use, unhealthy diet, physical inactivity, and exposure to certain chemicals or radiation.
What is a tumor?
A tumor is an abnormal mass of tissue that results from the excessive division of cells.
What is the difference between benign and malignant tumors?
Benign tumors are non-cancerous and do not invade nearby tissues, while malignant tumors are cancerous and can invade nearby tissues and spread to other parts of the body.
What is metastasis?
Metastasis is the process by which cancer cells spread from the primary tumor to other parts of the body through the bloodstream or lymphatic system.
What are the main types of cancer treatment?
The main types of cancer treatment include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, and hormone therapy.
What is chemotherapy?
Chemotherapy is a cancer treatment that uses drugs to kill cancer cells or stop them from dividing.
What is immunotherapy?
Immunotherapy is a type of cancer treatment that helps the immune system fight cancer.
What are the major challenges in cancer research?
Some major challenges in cancer research include finding effective treatments for different types of cancer, identifying early detection methods, and understanding the underlying causes of cancer.
What are the signs and symptoms of cancer?
Signs and symptoms of cancer vary depending on the type and stage of cancer, but some common signs include unexplained weight loss, fatigue, pain, and changes in the skin.
How can cancer be prevented?
Some ways to prevent cancer include adopting a healthy lifestyle, avoiding tobacco products, protecting yourself from the sun, and getting vaccinated against cancer-causing infections.
What is the role of genetics in cancer development?
Genetic mutations can increase a person's risk of developing certain types of cancer. However, not all cancer cases are directly linked to inherited genetic mutations.
What is targeted therapy?
Targeted therapy is a type of cancer treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells.
What is the role of the immune system in cancer?
The immune system plays a crucial role in recognizing and destroying abnormal cells, including cancer cells. However, cancer cells can sometimes evade the immune system's defenses.
What are the stages of cancer?
Cancer is typically staged from 0 to 4, with 0 being the earliest stage and 4 being the most advanced stage. The stage of cancer helps determine the best course of treatment.
What are the different types of cancer?
