Cancer and Mitosis: Cancer is a complex disease that can occur when the normal process of cell division, like mitosis, goes wrong. Our bodies tightly control the process of cell division to ensure that new cells are created only when needed and that they have the correct genetic information. However, sometimes mistakes happen during mitosis that can lead to uncontrolled cell growth.
Cancer begins when a single cell or a small group of cells start to divide uncontrollably, forming a mass of cells called a tumor. These cells might not properly mature into specialized cells, and they can invade nearby tissues or spread to other parts of the body.
Why It Happens to Some and Not Others: Cancer can happen for various reasons, and it's often a result of a combination of factors:
Genetics: Some people are more prone to developing cancer due to inherited gene mutations that increase their risk.
Environmental Factors: Exposure to things like tobacco smoke, certain chemicals, radiation, and unhealthy diets can increase the risk of cancer.
Lifestyle Choices: Unhealthy habits like smoking, excessive sun exposure, poor diet, and lack of exercise can contribute to cancer risk.
Age: As we get older, the risk of cancer generally increases.
Immune System: A weakened immune system might have trouble controlling the growth of abnormal cells.
Preventing Cancer: Teenagers can take steps to lower their risk of cancer:
Healthy Diet: Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help lower the risk.
Physical Activity: Regular exercise helps maintain a healthy body weight and reduces the risk of certain cancers.
Sun Protection: Using sunscreen, wearing protective clothing, and avoiding excessive sun exposure can reduce the risk of skin cancer.
Avoiding Harmful Substances: Avoiding tobacco products and limiting alcohol intake can greatly lower the risk of many types of cancer. Do not start smoking.
Vaccinations: Some vaccines, like the HPV vaccine, can protect against infections that increase the risk of certain cancers.
Regular Check-ups: Regular health check-ups and screenings can help catch any potential issues early.
Limiting Radiation Exposure: Minimize unnecessary exposure to sources of radiation.
Stress Management: Finding healthy ways to manage stress can support overall well-being.
Remember, while it's not always possible to completely eliminate the risk of cancer, making healthy choices can significantly lower the chances of developing this disease. It's important to start adopting these habits early in life for long-term benefits.
