Why Cancer cannot be cured so easily?

Cancer is the uncontrolled growth of abnormal cells anywhere in a body.

There are over 200 types of cancer.

Anything that may cause a normal body cell to develop abnormally potentially can cause cancer; general categories of cancer-related or causative agents are as follows: chemical or toxic compound exposures, ionizing radiation, some pathogens, and human genetics.

Cancer symptoms and signs depend on the specific type and grade of cancer; although general signs and symptoms are not very specific the following can be found in patients with different cancers: fatigue, weight loss, pain, skin changes, change in bowel or bladder function, unusual bleeding, persistent cough or voice change, fever, lumps, or tissue masses.

Cancer facts:

1. Sleep :

This is a cancer fact that many don’t see coming. Sleep deprivation – defined as getting less than six hours of sleep per day – increases your risk of colon cancer. Recent studies also showed a higher risk of cancer among those who work night shift schedules. It makes sense. The benefit of healing sleep is one of the most underestimated ways to keep your body strong and cancer-free.

2.Mortality :

Globally, one in every eight deaths is caused by cancer. A painful cancer fact is that this disease causes more deaths than malaria, tuberculosis, and AIDS combined. Approximately 70% of cancer deaths occur to those of low and middle incomes. In the United States, cancer is listed as the cause in close to 1/4 of all deaths and is the leading cause of death in people aged 45-64 according to the CDC. Currently, there are about 33 million cancer survivors around the world (within 5 years of diagnosis).

3.Age :

In economically developed countries, 58% of cancer diagnoses are in people 65 years of age or older. In developing countries, people over 65 account for 40% of new cancer cases.

4.Obesity :

Research has confirmed that obesity increases your risk of cancer as well as every other major disease or condition. It can also affect your chances of survival should you be diagnosed. In one study of post-menopausal women with breast cancer, the survival rates were higher in women who maintained a healthy body weight. Prediabetes increases your risk of cancer by 15% in addition to the risk from obesity. In the United States, two-thirds of the population is considered overweight or obese. It is estimated that half of all American adults have diabetes or pre-diabetes and many might not realize they have it.

5.Nutrition :

What you eat matters. The most common cancer-causing foods are refined sugar and flour, soda, microwave popcorn, food in cans produced with BPA, grilled or processed meat, and hydrogenated oils. The choices you make every day can raise or lower your personal cancer risk. As mentioned in #16, there are specific foods that trigger damaged cells (such as those that lead to cancer) to self-destruct via apoptosis. Green tea, berries, turmeric, avocados, garlic, kale, and even dark chocolate are just a few that target and destroy cancer cells. You can prevent and fight cancer from the inside out!

Treatment

CAR T CELLS are the equivalent of “giving patients a living drug,” explained Renier J. Brentjens, M.D., Ph.D., of Memorial Sloan Kettering Cancer Center in New York, another early leader in the CAR T-cell field.

As its name implies, the backbone of CAR T-cell therapy is T cells, which are often called the workhorses of the immune system because of their critical role in orchestrating the immune response and killing cells infected by pathogens. The therapy requires drawing blood from patients and separating out the T cells. Next, using a disarmed virus, the T cells are genetically engineered to produce receptors on their surface called chimeric antigen receptors, or CARs.
