Cancer is a complex and devastating disease that affects millions of people around the world. It is characterized by uncontrolled and abnormal growth of cells in the body, which can lead to the formation of malignant tumors. As these cancer cells multiply, they can invade surrounding tissues and organs and damage them, disrupting their normal function.
Cancer starts in cells basic units of life. The human body is made up of trillions of cells that are constantly dividing and renewing to maintain health and function. Normally, this process is regulated by internal mechanisms that provide the right balance between cell division and programmed cell death, known as apoptosis. However, in cancer, there is a dangerous imbalance that leads to uncontrolled cell proliferation.
Cancer can occur for a variety of reasons, but in general, the risk is higher if you lead an unhealthy lifestyle. The underlying causes are varied and often associated with genetic changes or mutations in the DNA of cells. These mutations may be inherited from previous generations or may occur during life due to environmental factors such as exposure to cancer-causing substances, radiation, or even random errors in DNA replication. These genetic changes can affect genes responsible for regulating cell growth and suppressing tumors. allowing cells to become cancerous and evade normal controls.
“Cancer can start anywhere in the human body, which is made up of trillions of cells. Under normal conditions, human cells form and multiply (through a process called cell division), producing new cells as they are needed. As cells age or become damaged, they die and are replaced by new cells,” explains the US National Cancer Institute.
“Sometimes the process doesn’t follow that order, and abnormal cells or damaged cells form and multiply when they shouldn’t. These cells can form tumors, which are lumps of tissue. Tumors are either cancerous (malignant) or non-cancerous (benign). Cancer tumors spread (or invade) nearby tissues. They can also travel further to other parts of the body and form tumors, a process called metastasis.
Although some types of cancer cause the same symptoms, the vast majority of them produce different signals in the body. It is worth mentioning in this line that there is a variety of this disease in which one of its symptoms appears during the day.
It is lung cancer that starts in this organ and is the leading cause of cancer death worldwide. A symptom that usually appears during the dayaccording to the digital platform La Vida Lúcida, This is pain or discomfort in the chest.
If a person experiences chest pain or discomfort for several days in a row, they should urgently go to a certified medical center for appropriate medical tests to confirm or rule out lung cancer.
About lung cancer
Lung cancer begins when cells in the lungs begin to undergo genetic mutations that disrupt their normal life cycle. These mutations may be the result exposure to risk factors such as smoking, long-term exposure to tobacco smoke, air pollution, exposure to radon (a radioactive gas present in the soil and in some homes) and other environmental carcinogens. Because these mutated cells divide and multiply uncontrollably, they can form tumors that interfere with the normal functioning of the lungs and, in advanced stages, can metastasize to other parts of the body.
Prevention plays a vital role in the fight against lung cancer. Here are some key measures to reduce your risk of developing this disease:
- Quit smoking: Smoking is the most important risk factor for developing lung cancer. Quitting smoking is the most effective risk-reducing action. Even people who have smoked for many years may benefit from quitting, as the risk decreases over time after quitting.
- Avoid exposure to tobacco smoke: Passive smoking can also increase the risk of lung cancer. Avoid places where people smoke and promote a smoke-free environment.
- Protection against exposure to radon: Radon is an invisible, odorless gas that can seep out of the ground and accumulate in buildings. Checking homes and workplaces for radon and, if necessary, taking steps to reduce radon levels can reduce the risk.
- Limit exposure to environmental pollutants: Reducing exposure to air pollutants such as vehicle emissions and industrial pollution can help reduce risk.
- Lead a healthy lifestyle: A balanced diet rich in fruits, vegetables, and whole grains, as well as regular physical activity, can help prevent lung cancer.
- Regular medical check-ups: People with risk factors, such as smokers or people with a family history of lung cancer, may benefit from regular physical exams and screening tests, such as low-dose CT scans.
