Introduction
Cancer is one of the leading causes of death worldwide, and lung and colorectal cancer are two of the most common types. In fact, according to the World Health Organization, lung and colorectal cancer are now the leading causes of cancer-related deaths. While there is no surefire way to prevent these cancers, there are certain lifestyle changes you can make to reduce your risk. Eating a healthy diet, exercising regularly, and avoiding certain foods and drinks can all help reduce your risk of developing these cancers. In this article, we’ll discuss what to watch for when it comes to lung and colorectal cancer, and provide some tips on what to eat and what to avoid.
Lung and Colorectal Cancer Now Cause the Most Deaths. Here’s What to Watch For
Lung and colorectal cancer are now the leading causes of cancer death in the United States, according to the American Cancer Society. In 2020, an estimated 228,820 people will die from lung cancer and 145,600 from colorectal cancer.
These two cancers are responsible for more than one-third of all cancer deaths in the United States. While the death rate from cancer overall has been declining since the early 1990s, the death rate from lung cancer has been increasing since the mid-1980s.
The good news is that there are steps you can take to reduce your risk of developing these cancers. Here are some things to watch for:
Lung Cancer
- Smoking: Smoking is the leading cause of lung cancer. If you smoke, quitting is the best way to reduce your risk.
- Radon: Radon is a naturally occurring gas that can accumulate in homes and other buildings. It is the second leading cause of lung cancer. Have your home tested for radon and take steps to reduce your exposure if necessary.
- Air pollution: Long-term exposure to air pollution can increase your risk of lung cancer. Avoid exercising outdoors when air pollution levels are high.
Colorectal Cancer
- Diet: Eating a diet high in red and processed meats, as well as foods high in fat and sugar, can increase your risk of colorectal cancer. Eating a diet rich in fruits, vegetables, and whole grains can help reduce your risk.
- Physical activity: Regular physical activity can help reduce your risk of colorectal cancer. Aim for at least 30 minutes of moderate-intensity activity most days of the week.
- Screening: Regular screening for colorectal cancer is important. Talk to your doctor about when to start and how often to get screened.
By taking steps to reduce your risk of lung and colorectal cancer, you can help reduce your risk of dying from these diseases. Talk to your doctor about what you can do to reduce your risk.
A new report by the American Cancer Society finds that lung and colorectal cancers cause the most deaths of any cancer, and the trend is likely to continue in 2023.
Overall, the rate of cancer deaths has dropped 33 percent — nearly 3.8 million lives — since 1991, the society reports. But the society projects nearly 2 million new cancer cases and more than 600,000 U.S. deaths for this year.
Here’s what to look for to avoid becoming one of the people to succumb to lung or colorectal cancer.
You have a much higher chance of developing lung cancer if you smoke.
Beyond that, common symptoms include the following: A persistent cough that worsens, chest pain, wheezing or an inability to breathe, coughing up blood or chronic fatigue.
Lung cancer can also lead to recurrent infections such as bronchitis or pneumonia.
You should consult a doctor if this describes you.
Once lung cancer spreads to the rest of the body, it can cause symptoms elsewhere.
These include pain in the back or hip bones; neurological symptoms such as dizziness, weakness or numbness; jaundice of the skin or the whites of the eyes; or lymph node swelling.
Lung cancer can lead to several other syndromes that have characteristics of their own.
They include Horner syndrome, which involves tumors in the upper part of the lung and can affect nerves of the face or eye. It manifests as drooping eyelids, small pupils and even shoulder pain.
Superior vena cava syndrome involves tumors of the large blood vessel that connects the heart with the head and arms. It can lead to swelling or edema of the upper body, including the face, as well as other neurological symptoms.
There are several other syndromes linked to lung cancer that your doctor can explain to you.
Colorectal cancer can go undiagnosed well before symptoms appear. The federal government recommends early screening to catch it before symptoms appear.
It suggests that adults from 45 to 75 get screened. Above 75, you should discuss screening with your doctor.
Screening can include stool tests either in your doctor’s office or through a home test once every three years.
In-office tests can include flexible sigmoidoscopy, in which a doctor inserts a lighted tube into the rectum to check for polyps or cancer in the lower third of the colon, and full colonoscopy, which uses a longer tube to check the entire colon.
Such tests are recommended once every five or 10 years, depending on whether stool tests are conducted in intervening years. Ask your doctor when and how frequently you should get screened.
Once colorectal cancer symptoms occur, they can include the following: a change in bowel habits, including diarrhea or constipation; rectal bleeding or blood in the stool; pain or cramps in the abdomen; or unintended weight loss.
Symptoms can also include a feeling that you need to have a bowel movement that doesn’t go away even after one. Another common symptom is a low red blood cell count.
If you have any of these symptoms, you should consult your doctor.
