Cancer Symptoms and Treatments
While symptoms of cancer may differ from patient to patient, most types can be identified by your physician. Your doctor will ask you questions about your symptoms and medical history, and may order tests to check for the underlying cause of your symptoms. Because many cancers are detected through screening tests, cancer can be discovered even if you have no symptoms. Common cancer screening tests include mammography, colonoscopy, and Pap tests. However, these tests are not 100% accurate, and they may show symptoms that are not related to cancer.
Generally, cancer occurs when cells of the body divide uncontrollably. Healthy cells in the body grow and replace old ones, but cancer cells multiply uncontrollably. These cells eventually form tumors and crowd out normal cells in the bloodstream. As these cells multiply uncontrollably, they start to interfere with the normal function of important organs. Healthy cells grow and replace damaged ones, but cancer disrupts this process, causing abnormal new cells to develop. These cells grow too quickly and cause damage to surrounding healthy tissues.
A person’s genetic code determines when cells divide and expire. However, some genes are permanently switched on, leading to faulty instructions and a cancerous tumor. While most cancers occur in solid tumors, some cancers occur in the blood and don’t form tumors. These cancers differ from normal cells in several ways. Cancer cells can cause organ failure and damage, and cancer tumors can even lead to death. Cancer is the most common form of disease-related death.
The oldest form of cancer treatment is surgery. Approximately 3 out of 5 people with cancer will undergo surgery. Surgical procedures often involve the removal of healthy cells that surround the tumor. The aim of the treatment is to cure the cancer, and to prevent it from returning. Some people may have no symptoms until it is treated. If this is the case, additional treatments may be needed to keep the cancer cells from spreading again. When treatment is successful, patients should feel normal and confident about their appearance.
Once cancer cells have spread throughout the body, they will often travel through the bloodstream. Once they reach these distant areas, they will continue to grow, eventually forming new tumours. This process is known as metastasis. This process is similar to the way that chickenpox spreads to other areas of the body. It is rare for a child to develop cancer in a large crowd of children. However, if the cancer has spread to bone, it is usually referred to as bone cancer.
When cells replicate DNA, errors are inevitable. These errors are repaired by complex error correction mechanisms. Nonetheless, cancer cells can develop mutations in these DNA repair genes. If this happens, they develop additional mutations and chromosome changes that make them cancerous. Therefore, cancer treatments are based on targeting these mutations. However, it is still impossible to eliminate the underlying causes of cancer. And, despite this, the chances of success are increasing every day.
