<p>Do you know what is cancer and how a cancerous cell affects you? Cancer awareness is vital to save the lives of millions around the world. Read to learn more!</p><h2>What is cancer?</h2><p>Cancer is a group of life-threatening diseases. It forms when abnormal cells grow uncontrollably and spread to different parts of the body. Your body is made up of trillions of cells. It is normal for human cells to grow and multiply as your body requires them. This process is called cell division. New cells replace the damaged or dead cells. Cancer is diagnosed when abnormal body cells spread in an uncontrolled manner.</p><p>Cancer is the second leading cause of mortality worldwide. Lung, colorectal, liver, and prostate cancer are some common types of cancer in men. Breast, cervical, and thyroid cancer are common among women.</p><p>Now that you know what is cancer, have you ever wondered how cancer develops? Cancer may develop when the control mechanism of your body stops functioning or if there are genetic changes in the process. Here, older and damaged cells grow out of control instead of dying. This leads to the formation of new abnormal cells. The abnormal cancerous cells form a mass known as a tumor. However, certain cancers such as leukemia do not lead to the formation of tumors. Cancer can form in any part of your body.</p><h2>Causes of cancer</h2><p>Below are certain risk factors that may act as the causes of cancer:</p><h3>Genetic changes</h3><p>The mutation of DNA in your cells can cause cancer. DNA contains instructions for the cells on what functions to perform and how to grow and divide. An error in these instructions can prevent cells from functioning normally. This gives rise to cancerous cells. A cancerous cell fails to stop and keeps growing.</p><h3>Family history</h3><p>Some early signs of cancer can occur due to inheritance. A family history of cancers can put you at risk of several types of cancers.</p><h3>Age</h3><p>Although cancer can occur at any age in your life, it is more commonly diagnosed in older people. Typically, it affects people older than 65 years of age. This is because several types of cancer can take years to develop.</p><h3>Viral and bacterial infections</h3><p>Several bacterial and viral infections can cause certain types of cancer. For instance, the human papillomavirus (HPV) is associated with cervical cancers, penile cancers, and some head and neck cancers. Similarly, cancer such as liver cancer is linked with exposure to Hepatitis A and Hepatitis B virus.</p><h3>Unhealthy habits</h3><p>Lifestyle choices such as smoking, excessive drinking of alcohol, exposure to the sun, being obese, unprotected sexual intercourse and more can put you at risk.</p><h3>Environment</h3><p>Factors such as exposure to secondhand smoke, harmful industrial chemicals, occupation, and unhealthy health conditions can increase your risk.</p><h2>Early signs of cancer</h2><p>The signs of cancer may differ for the different types of cancer.
