Frequently Asked Questions

QWhat exactly is cancer?

Cancer's a tricky disease where cells in your body start to grow uncontrollably. Normally, cells grow, divide, and then die when they're old or damaged. But with cancer, this process goes haywire. Instead of dying, these rogue cells keep on multiplying, forming what we call tumors, or in the case of blood cancers, crowding out normal cells in the blood.

QHow many types of cancer are there?

Believe it or not, there are over 100 different types of cancer. Each type is usually named after the organ or type of cell where it first starts. For example, lung cancer begins in the lung, and leukemia starts in the blood cells.

QCan cancer spread to other parts of the body?

Yep, it sure can. This process is known as metastasis. Cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. That's why catching it early is so crucial.

QWhat are some common signs of cancer?

Signs can vary widely depending on the type, but some common ones include unexplained weight loss, fever, fatigue, pain, skin changes, and changes in bowel or bladder habits. Always best to check with a doctor if you're noticing anything unusual.

QIs cancer genetic?

In some cases, yes. Certain types of cancer can be passed down from one generation to the next through our genes. However, most cancers develop because of mutations that happen over a person's lifetime due to environmental factors or simply by chance.

QHow can you reduce your risk of getting cancer?

Living a healthy lifestyle is key. This means eating plenty of fruits and veggies, staying active, avoiding tobacco, limiting alcohol, protecting your skin from the sun, and getting regular check-ups and screenings. No guarantee, but these habits can significantly lower your risk.

QWhat's the deal with cancer treatment?

Treatment varies wildly depending on the type and stage of cancer. Options might include surgery, radiation therapy, chemotherapy, immunotherapy, or a combination of these. Researchers are always working on new treatments, so there's always hope on the horizon.

QCan cancer be prevented?

While there's no surefire way to prevent cancer entirely, you can definitely take steps to significantly reduce your risk. Avoiding known carcinogens, leading a healthy lifestyle, and getting regular screenings for certain types of cancer can make a big difference.
