Normally, our body makes new cells when needed and removes old or damaged cells. But sometimes, this natural process stops working properly. As a result, the damaged cells keep growing and may form a lump called a tumor. Some cancers also spread to other parts of the body through the blood or lymph system.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Healthy_Cells_vs_Cancer_Cells\"><\/span><b>Healthy Cells vs Cancer Cells<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Healthy cells grow in a controlled way.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Healthy cells die when they become old or damaged.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cancer cells keep growing even when they should stop.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cancer cells can spread to the nearby organs and other body parts.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Why_Cancer_Occurs_Understanding_the_Basics\"><\/span><b>Why Cancer Occurs: Understanding the Basics<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Many people ask <\/span><b>what causes cancer<\/b><span style=\"font-weight: 400;\">. The simple answer is that cancer starts when the DNA inside our cells gets damaged. DNA gives instructions to every cell about how to grow and work. If these instructions change, the cells may begin to grow in an abnormal way. This is one of the main reasons <\/span>why cancer occurs. These changes can happen because of inherited genes, harmful chemicals, smoking, infections, or long-term unhealthy habits.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_Main_Causes_of_Cell_Damage\"><\/span><b>The Main Causes of Cell Damage<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Changes in the DNA over time<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Long-term use of tobacco<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Exposure to harmful chemicals<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Radiation from the sun or other sources<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Certain viral infections<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Unhealthy daily habits<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Understanding these causes of cell damage is important, as each one acts as a <\/span><b>cancer risk factor<\/b>https:\/\/hiims.in\/blog\/cancer-risk-factors\/<span style=\"font-weight: 400;\"> that can be reduced with the right awareness and lifestyle choices.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Common_Cancer_Causes_Genetic_Lifestyle_and_Environmental_Risks\"><\/span><b>Common Cancer Causes: Genetic, Lifestyle, and Environmental Risks<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Understanding the <\/span><b>causes of cancer<\/b><span style=\"font-weight: 400;\"> helps us know which risks we can reduce and which ones we cannot control.
