What Everyone Should Know About Cancer

Cancer is one of the most talked-about health challenges in the world, yet many people still don’t fully understand it. With today being World Cancer Day, it’s the perfect time to learn the basics, what cancer is, what causes it, and how we can prevent and fight it.

Cancer happens when cells in the body grow uncontrollably. These cells can form tumors or spread to other parts of the body, a process known as metastasis. However, not all tumors are cancerous, some are benign and do not spread. 

There are over 100 types of cancer, affecting different parts of the body, including the lungs, breasts, prostate, and blood (like leukemia).

How Common Is Cancer?

Cancer affects millions of people worldwide. According to health experts:

• 1 in 2 men and 1 in 3 women will be diagnosed with cancer at some point in their lives.
• Every year, millions of new cases are reported globally.
• Some cancers are more common than others, with lung, breast, and colorectal cancer being among the leading types.

What Causes Cancer?

Cancer is caused by changes (mutations) in the body’s cells. While some of these changes are inherited, most happen due to lifestyle and environmental factors. 

Common risk factors include:

Smoking – The biggest cause of lung cancer.
Unhealthy diet – Processed foods and sugary drinks increase the risk.
Obesity – Being overweight is linked to many types of cancer.
Alcohol consumption – Excessive drinking raises the risk.
Sun exposure – UV rays can cause skin cancer.
Genetics – Some people inherit cancer-causing mutations, but lifestyle still plays a huge role.

How cancer be prevented

The good news is that many cancers are preventable. Small lifestyle changes can make a big difference:

Quit smoking – Reduces lung and throat cancer risks.
Eat a healthy diet – Focus on fruits, vegetables, and whole grains.
Exercise regularly – Staying active lowers cancer risk.
Limit alcohol intake – Less alcohol, lower risk.
Use sunscreen – Protect your skin from harmful UV rays.
Go for regular check-ups – Early detection saves lives!

Why early detection matters

Many cancers don’t show symptoms in the early stages, making regular screening important. Tests like mammograms, colonoscopies, and Pap smears can help catch cancer before it spreads. The earlier cancer is found, the better the chances of successful treatment.

The fight against cancer is ongoing, but thanks to new treatments and medical advancements, survival rates are improving. Research into immunotherapy, targeted therapies, and early detection methods is giving patients more hope than ever before.
