Cancer is a disease where some cells in our body grow uncontrollably and don’t die when they should. Normally, cells grow and divide, then die when they get old or damaged, making way for new cells. But with cancer, this process breaks down, and the bad cells keep growing. They can form lumps called tumors, or spread to different parts of the body.
There are many types of cancer, like breast cancer, lung cancer, and skin cancer, and they can happen almost anywhere in the body. Some cancers grow fast, while others are slower.

Symptoms of Cancer :
Cancer symptoms depend on where the cancer is in the body, but some common signs include:
Lumps: If you feel a lump or swelling that doesn’t go away, especially in places like the breast or neck.
Unexplained Weight Loss: Losing weight without trying is a common symptom of cancer.
Persistent Cough: A cough that doesn’t go away or brings up blood can be a sign of lung cancer.
Changes in Skin: Darkening or yellowing of the skin, or a mole that changes in shape or color.
Unusual Bleeding: Bleeding that is not normal, like between periods, after menopause, or when going to the bathroom.
If you notice any of these symptoms, it’s important to see a doctor.

2. Quit Smoking: If you smoke, quitting is one of the best things you can do to reduce the risk of lung and other cancers.
3. Protect Your Skin: Wear sunscreen when you’re outside, and try to stay in the shade to protect your skin from harmful UV rays.
4. Regular Check-Ups: Early detection is key. Regular doctor visits and screenings can catch cancer early, when it’s easier to treat.
5. Vaccinations: Some vaccines, like the HPV vaccine, can protect against cancers caused by viruses.
Treating Cancer
If someone has cancer, there are different ways to treat it. The treatment depends on the type of cancer and how far it has spread. Here are the most common treatments:
Surgery: Doctors can remove tumors or the part of the body with cancer.
Chemotherapy: This is medicine that kills cancer cells or stops them from growing. It can make people feel sick, but it’s often very effective.
Radiation Therapy: High-energy rays are used to target and kill cancer cells.
Immunotherapy: This boosts the body’s own immune system to fight cancer.
The earlier cancer is found, the easier it is to treat. That’s why it’s so important to live a healthy life and pay attention to any changes in your body.
Conclusion
Cancer can be scary, but knowing the causes and symptoms helps you protect yourself. By making healthy choices and going to regular check-ups, you can lower your risk. And if cancer is found, doctors have many ways to treat it, especially when caught early.
