The deadliest cancer and most dangerous type of cancer

What is the deadliest cancer? and which type is the most dangerous cancer? In this article, we will learn about the most dangerous type of cancer that kill millions of people annually.

We will also explain the rate of spread of the disease among people and the factors that increase the chances of developing cancer.

In addition to taking an idea of ​​the tests that may be needed to confirm the presence of the disease. with knowledge of cure rates and expectations of survival The patient is diagnosed with one of the types.

What is the deadliest cancer? and which type is the most dangerous cancer?

The deadliest cancer and most dangerous type of cancer is Lung cancer.

Lung cancer overview

Lung cancer originates in the lungs, which are the two main organs of the human respiratory system, in which gas exchanges occur with every breath that a person inhales and exhales. as the lung receives oxygen upon inhalation and disposes of carbon dioxide upon exhalation.

This cancer is the number one cause of cancer death in the world both among men and women.

it can be said that the cause of lung cancer is well known and the number of deaths it causes can be reduced if strict measures are taken, that reason is smoking, where smokers make up about 90% of Lung cancer cases.
It is the number one cause of cancer death, but it is not the most common.

How common is lung cancer?

Lung cancer (both small cell lung cancer and non-small cell lung cancer) is the second most common cancer in men and women (not including skin cancer), prostate cancer is more common in men, and breast cancer is more common in women. The number of lung cancer cases is expected to reach 2.2 million in 2020.

The American Cancer Society’s predictions for lung cancer in the United States for 2020 are:

More than 228,000 new cases of lung cancer (116,000 in men and 112,000 in women).
More than 135,000 deaths from lung cancer (72,000 in men and 63,000 in women).

Lung cancer occurs mainly in the elderly, most people diagnosed with lung cancer are 65 years of age or older.

small numbers of people are diagnosed with lung cancer at the age of less than 45 years, the average age of people when the disease is discovered is 70 years.

Deaths due to deadliest lung cancer:

Lung cancer is the leading cause of cancer death in both men and women, and accounts for approximately 25% of all cancer deaths. Each year more people die from lung cancer than from colon, breast and prostate cancer combined.

The number of lung cancer deaths globally reached 1.76 million in 2018, this number is expected to increase to 1.86 million in 2020 and may reach 2.45 million in 2030.

There is certainly a general improvement in the status of lung cancer cases, partly due to smoking cessation and making great strides in early detection mechanisms and treatment methods. However, all of this is not enough so far.

The number of cases and deaths is still constantly rising. Strong measures must be taken if there are A real will to reach tangible results in lowering the rates of new cases and deaths.

Lung cancer risk

In general, the chance of a man developing lung cancer in his lifetime is 1 in 15 men; For women, the risk is 1 in 17 women. These percentages include both smokers and non-smokers.

For smokers, the risks are much higher compared to non-smokers, where the risks are lower and by a large margin, as we previously explained that smokers represent about 90% of lung cancer cases.

Survival statistics for people with lung cancer vary depending on the stage of the cancer when it was diagnosed.

What puts people at risk?

Smoking causes The deadliest cancer

There are some factors that increase the chances of developing lung cancer, the most important of which is smoking, as it is a controllable factor and the main cause behind lung cancer.

We also include here passive smoking (inhaling someone else’s smoke), for example, a father’s smoking in the presence of his children exposes them all to risk. .

If you’ve had a previous diagnosis of lung cancer in your family, this also increases your chances of developing it.

If you’re exposed to radon (which is usually released from the natural decomposition of soil and water) and some other chemicals (asbestos, arsenic, chromium, nickel, tar).

Lung cancer is more common in people with HIV. Experts don’t know why… This is likely because the mechanisms of the immune system are destroyed and the cells of the immune system normally have the task of destroying them easily defective.

Are there screening tests for deadliest lung cancer?

Yes, but doctors do not recommend routine screening for everyone because it may reveal non-malignant tumors but requires many tests to be sure and this puts some people at risk unnecessarily.

Recently, there have been some recommendations indicating that tests such as x-rays and computed tomography of the lung can be done for heavy smokers (more than 30 cigarettes per day in the last 15 years or more) who are over 55 years old and up to 77 years old.

If I’m diagnosed with lung cancer, what is the outlook?

Lung cancer Like other cancers that are easily treated and found early. survival varies depending on both the type of lung cancer you have (small cell lung cancer and non-small cell lung cancer) and the stage of the cancer.

overall only 17% Alive 5 years after being diagnosed, this number doesn’t say everything because there is a variance in the chances of survival depending on the degree of lung cancer.

For people with ‘local’ cancer (that hasn’t spread i.e. it’s confined to its place). about 54% have been able to survive 5 years after finding it.

if it has metastasized to parts close to where the cancer originated but not far, still about 25% Survival after 5 years. and in patients whose lung cancer has spread to distant areas of their body, only about 4% manage to survive for 5 years.
