Cancer is the disease of the century; you may disapprove and think that the Covid-19 is this century’s disease, but it is said that cancer was discovered around 1500 BC, yet there is no concrete cure.

Most cancers are still very difficult to diagnose, and as it is diagnosed behindhand, the illness is already at an advanced stage, very aggressive, consequently no effective treatment. Even though not every cancer causes death, there is still a high death rate. One would have thought that there would be a cure with the advancement of the medical industry by now.

According to the American Cancer Society, in 2021, more than 1,6 million people will be diagnosed with cancer in the United States, and half of them will lose their lives.

Lung Cancer

Lung cancer is the second most common cancer, but it is the deadliest. It is mostly diagnosed in older people (65 years and over); nevertheless, there is a small number of young people diagnosed with lung cancer. It makes up at least 25 % of all cancer deaths.

The number one cause of lung cancer remains smoking, be it cigarettes, pipes, or cigars… Keep in mind that being a passive smoker can also lead to lung cancer, daily exposition to strong substances, and a family history of lung cancer.

Noticeable symptoms are:

Coughing

Chest pain

Difficulty breathing

Tiredness

Colorectal Cancer

Colorectal, which can be called colon or rectal cancer, is the third most diagnosed cancer. The number of people dying from colorectal cancer has dropped during the past years as people are now getting screened; thus, the illness is detected sooner. In 2021, colorectal cancer is expected to count more than 50 000 deaths.

There is a high risk for a consumer of a high-fat diet, processed meat or red meat. Gene mutations acquired or inherited can both lead to cancer.

Noticeable symptoms:

Changes in bowel habits

Rectal blooding

Frequent cramping

Fatigue

Breast Cancer

Breast cancer is expected to cause 44 130 deaths in 2021 alone. Breast cancer is the second most common cause of death for women; the first one is lung cancer. There are different types; tumor, node, and metastasis. So these types can be at different stages, from 0 to 4.

Breast cancer can be inherited, so if there is a history of breast cancer in the family, it is better to go for screening, but it can be sporadic too, which means there is existing damage in the person’s genes.

Noticeable symptoms:

Breast or underarm lump.

Nipple’s pain.

Changes in breast size or shape.

Pancreatic Cancer

Pancreatic cancer, as the name tells, is built within the cells of the pancreas. Comparatively, it is rare cancer, and the few cases mostly lead to death. Statistics reveal that only 8.5 % of pancreatic patients live five years after their diagnosis.

One of the reasons pancreatic cancer patients have a low survival rate is that only 10 % are detected early and can be removed by surgery. Pancreatic cancer has the most probability of spreading to other parts.

Common symptoms:

Jaundice

Dark pee

Tiredness

Changes in bowel habits.

Prostate Cancer

Americans die from prostate cancer more than any other type of cancer, right after lung cancer. One in 41 men will develop prostate cancer. While it can affect anyone, prostate cancer is more prevalent in older men.

The five-year survival rate for prostate patients is high, but there is no way to get rid of it; either it grows slowly or grows quickly and aggressively.

Common symptoms:

Burning sensation when urinating or ejaculating.

Erectile dysfunction.

Blood presence in the semen or urine.

Urges to pee.

All of the cancers mentioned above can be managed if found earlier. However, for lung cancer, it depends on what type of cancer the patient has. It is also important to know whether cancer has spread to others that can be recurrent. All of the information above is the big picture, but each case is different.
