What is cancer? Cancer is a disease that takes over different parts of the body and prevents them from functioning properly. It can grow and spread to other parts of the body. A tumor is an example of cancer cells that have grown excessively and are affecting surrounding tissue and organs, preventing them from fulfilling their functions.
Cancer can occur anywhere in the body but usually starts in one specific area, such as the breast, lung, colon, or skin. The most common types include colorectal cancer (in your colon or rectum), prostate cancer (in men), breast cancer (in women), liver cancer (hepatoma) as well as skin cancers like melanoma and basal cell carcinoma. Cancer can also be classified by what kind of cell is affected. There are about 100 different types of cancer. Ultimately, cancer is a disease that affects people of all ages. It is not a disease of one particular age group or gender. Cancer can affect anyone.
What causes cancer?
Scientists divide the causes of cancer into two main categories:
Physical agents, including chemicals, radiation, viruses, and other physical factors; and Dietary factors, including eating habits and obesity. Numerous scientific studies have shown that there are links between diet and the risk of developing certain types of cancer. Lastly, cancer can be hereditary, meaning that it runs in families and can be passed down through generations.
How do we know if we have cancer?
The first step in identifying cancer is to look for symptoms. Cancer may not always present with symptoms and can go unnoticed until it is too late. If you are experiencing any of the following, see your doctor right away:
- Abdominal pain or discomfort
- Appetite changes
- Changes in bowel habits
- Bleeding or discharge from the vagina, rectum, or anus
- Blood in the stool or urine
- Bruising easily
- Cough
- Difficulty breathing
- Fever
- Weight loss
- Weakness
Cancer is caused by DNA mutations. DNA is the body's genetic material. Each cell contains 46 chromosomes. The chromosomes are the carrier of our genes, which are responsible for who we are and how our bodies function. The cell can divide into two daughters cells, each of which has 23 chromosomes. If the original cell has a mistake in its DNA, this will lead to an abnormal cell that can then grow uncontrollably and spread to other cells or organs in that person's body. This mistake is called a mutation, and cancer occurs because that mutation occurs in many different parts of the body at once.
The process by which this happens is known as "oncogenesis", meaning "tumor-generation". Oncogenesis is the abnormal development of cells in a variety of different organs and tissues. To stop cancer from spreading, many doctors suggest the patient undergoes chemotherapy or radiation therapy. Chemotherapy is a treatment that has been found to work best when chemotherapy drugs and radiation therapy are used together.
There are several factors that are thought to contribute to prostate cancer, including genetics, aging, the male hormone testosterone, diet, and environment. The risk of developing prostate cancer increases with age but is also influenced by genetics. About one in six men in the United States will be diagnosed with prostate cancer in their lifetime. Certain genes make people more susceptible to developing prostate cancer by increasing the likelihood of genetic changes occurring in cells, including gene mutations or rearrangements. Families who have a history of an inherited form of breast or colon cancer are at increased risk for prostate cancer.
In conclusion, while prostate cancer is not usually a major cause of death, early diagnosis and treatment can increase the chances of survival. The first step in the prevention of any illness is knowledge. It is imperative that you become familiar with the symptoms of cancer and learn how to detect them early. If you or someone you know is suffering from the symptoms listed below, get help. Your doctor or nurse will give you more information about cancer prevention and the best way to proceed. Symptoms of Cancer If you notice any of these symptoms, contact your healthcare provider: • Persistent unexplained fatigue. • Weight loss that isn't caused by dieting or exercise. • Lumps or masses anywhere on the body. • Swollen lymph glands. • Blood in urine or stool. • Vaginal bleeding. • Persistent pain that doesn't go away with simple remedies. • Difficulty swallowing or chewing. • Pain in your side (from a tumor), stomach, or abdomen. • Changes in your bowel habits, including a change in the color of your stool. • Changes in your sexual habits. • A change in your menstrual cycle, including more frequent or fewer periods. • Changes in your menstrual bleeding, such as blood clots or unusual amounts of blood.
Lifestyle choices are very important for maintaining health and preventing disease. As we mentioned above, smoking is the number one cause of cancer. The next three most common causes of cancer are: tobacco, diet and obesity, and alcohol use. It is important to eat a healthy diet and maintain a healthy weight to lower your risk of developing cancer.
There are several ways in which you can lower your risk of developing certain types of cancer. Smoking cigarettes and other tobacco products are strongly discouraged as it increases the risk of developing cancer and decreases your life expectancy. If you are a smoker, you may want to consider quitting. Another way to decrease your risk of developing cancer is to maintain a healthy weight. If you maintain a healthy weight, you will be less likely to develop diabetes or heart disease, both of which are associated with cancer. Maintaining a healthy weight means maintaining a healthy weight. Diet and exercise are two ways in which you can lower your risk of developing cancer. For example, you should avoid eating too much red meat, because red meat has been linked to higher levels of cancer-causing chemicals.
