Due to cancer, the cells become uncontrolled. This can cause tumours, damage to the immune system and other disorders that can be fatal.

According to the American Cancer Society’s 2018 report, in the United States, approximately 15.5 million people lived in cancer history by January 1, 2016.

In this article, we examine the types of cancer how the disease develops, and many treatments that help improve lives and survival rates.

What is cancer?

Cancer cells do not die on the natural point of the cell cycle.

Cancer is a comprehensive term. This describes the disease when uncontrolled growth occurs as a result of cellular changes and the cells are divided.

Some types of cancers rapidly cause cell growth, while the development of other cells and due to slow splitting.

In some forms of cancer, a view called tumour increases, while others, such as leukaemia, do not.

Most cells in the body have specific functions and fixed lifespan. Although it may look like a bad thing, cell death is part of a natural and beneficial event called apoptosis.

Instructions for the death of a cell have been given so that the body can replace it with a new cell that works better. Cancer cells lack the components that instruct them to split and stop them from dying.

Consequently, they produce in the body, use oxygen and nutrients, which usually nourish the other cells. Cancer-induced cells can form tumours, spoil the immune system, and can cause other changes that prevent the body from working on a regular basis.

Cancer cells can be seen in one area, then spread through the lymph nodes. These are the groups of immune cells located throughout the body.


There are many causes of cancer, and some are preventable.

For example, according to the figures outlined in 2014, more than 480,000 people smoker with American cigarettes every day.

In addition to smoking, cancer risk factors include:

Heavy intake of alcohol

Excess body weight

physical inactivity

poor nutrition

Other causes of cancer cannot be prevented. At present, the most important irreversible risk factor is age. According to the American Cancer Society, doctors in the US diagnose 87 percent of cancer cases in people 50 years of age or older.

Is Cancer Genetic?

Genetic factors can contribute to the development of cancer.

The genetic code of a person tells their cells when it is divided and finished. Changes in the genes can be faulty instructions, and cancer can occur.

Gene also affects the production of proteins of cells, and proteins give many instructions for cellular growth and division.

Some genes change proteins that usually repair damaged cells. This can lead to cancer. If a parent has these genes, they can pass the instructions sent on their instructions.

There are some genetic changes after birth, and factors like smoking and sun exposure can increase risk.

Other changes which can be the result of cancer, are in chemical signals that determine how the body changes, or “expresses” the specific genes.

Finally, a person can get pre-notification for a type of cancer. A doctor can refer to it being a hereditary cancer syndrome. The underlying genetic mutation contributes significantly to the development of 5-10 percent of cases of cancer.

The treatment

Innovative research has promoted the development of new drugs and treatment technologies.

Doctors generally determine the type of cancer, the phase of diagnosis, and treatment based on the overall health of the person.

Key-side effects

The side effects of chemotherapy include hair fall. However, progress in the treatment is improving the approach for people suffering from cancer.

Examples of cancer treatment approaches are given below:

The purpose of chemotherapy is to kill cancer cells with drugs that target rapidly dividing cells. Drugs can also help reduce a tumour, but side effects can be severe.

Hormonal therapy involves taking medicines that change how some hormones work or obstruct the body’s production capacity. When hormones play an important role with prostate and breast cancer, this is a general approach.

Immunotherapy uses medicines and other therapies to promote the immune system and to encourage cancer cells to fight. Two examples of these treatments are block and adoption of cell transfer.

Exact medication, or personalized medicine, is a new, developing approach. This includes the use of genetic testing to determine the best treatment for a person’s special cancer presentation. Researchers have not yet shown that it can effectively cure all types of cancers.

Radiation therapy uses high-dose radiation to kill cancer cells. In addition, a doctor may be able to shrink a tumour or reduce tumour-related symptoms before surgery.

Stem cell transplantation can be particularly beneficial for people related to blood-related cancer like leukaemia or lymphoma. This includes removing cells like red or white blood cells, which have destroyed chemotherapy or radiation.

A surgeon can remove lymph nodes to reduce or stop the spread of the disease.

Targeted therapy works within the cancer cells to prevent them from multiplying. They can also promote the immune system. Two examples of these treatments are small-molecule drugs and monoclonal antibodies.

According to the National Cancer Institute, the most common type of cancer is breast cancer, followed by lung and prostate cancer, which extends non-skin skin cancer through these conclusions.

Stop smoking

Smoking increases the risk of cancer.

Each year, more than 40,000 people detect one of the following types of cancers:

urinary bladder

Colon and rectum






non-Hodgkin’s lymphoma



Other forms are less common. According to the National Cancer Institute, there are more than 100 types of cancers.

Cancer development and cell division

Doctors classify cancer:

Its place in the body

Tissue that is in these forms

For example, sarcoma develops in bones or soft tissues, whereas carcinoma is formed in cells that cover internal or external surfaces in the body. Basal cell carcinoma develops in the skin, while adenocarcinoma can be formed in the breast.

When cancer cells spread to other parts of the body, then the medical term for it is a metastasis.

A person can have more than one type of cancer at a time.

Improvement in cancer detection increased awareness of the dangers of smoking, and the decline in the use of tobacco have contributed to the reduction of cancer diagnosis and the number of deaths annually in the years.

According to the American Cancer Society, between 1991 and 2015, the overall cancer mortality rate declined by 26 percent.
