Colorectal cancer begins in the large intestine (colon) or the rectum (end part of the colon). It usually affects older adults more, although it can occur at any age. It usually starts from a group of polyps or cells that form inside the colon, but can eventually lead to cancer.
Causes
According to the portal Medlineplus, colon cancer may be associated with a high-fat, low-fiber diet and high consumption of red meat.
Risk factor’s
As explained by the portal Mayo Clinic, factors that can increase the risk of colon cancer include the following:
- Although colon cancer can occur at any age, most patients with this condition are over 50 years of age.
- According to studies, African-Americans have a higher risk of colon cancer than people of other races.
- If you have already had colon cancer or non-cancerous polyps in the colon, you should be on the alert, as there is a high chance of getting this cancer again in the future.
- Chronic inflammatory diseases of the colon, such as ulcerative colitis and Crohn’s disease, can increase the risk.
- Hereditary syndromes can significantly increase the risk of colon cancer. Only a small percentage of cases are related to inherited genes.
- Colon cancer and rectal cancer may be associated with a diet that is low in fiber and high in fat and calories.
- Inactive people are more likely to develop colon cancer.
- People with diabetes or insulin resistance are at increased risk of colon cancer.
- Obese people have a higher chance of developing colon cancer, compared to people considered normal weight.
- smoking. People who smoke may be at increased risk of colon cancer.
- Alcohol. Excessive alcohol consumption increases the risk of colon cancer.
Lung cancer: these are the first symptoms
According to data from the World Health Organization (WHO), cancer is the leading cause of death in the world. In 2020, almost 10 million deaths from this disease were recorded. The most common types of cancer are those of the breast, lung, rectum, colon and prostate.
Lung cancer receives this name because it initially develops in these organs. However, it can later metastasize to other organs (spread).
The symptoms of this cancer can be different in each person. Symptoms usually manifest when the disease is in an advanced stage. In other patients, it can metastasize to other organs and cause other symptoms.
The Centers for Disease Control and Prevention mention some of them:
- Persistent or worsening cough.
- Chest pain.
- Difficulty breathing.
- wheezing
- Cough up blood.
- Feeling tired all the time.
- Weight loss with no known cause.
- Repeated crises of pneumonia.
- Swollen or enlarged glands.
There are two types of lung cancer: small cell lung cancer and non-small cell lung cancer. The former almost always develops in smokers. The second refers to a general term to refer to various types. Non-small cell lung cancer types include squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. indica Mayo Clinic.
