What is Cancer? Types, Symptoms, Causes

What is Cancer?

Our body is composed of many types of cells. As the body needs it, these cells divide and grow in a controlled way. But sometimes it happens that the body does not need these cells, yet it continues to grow. This abnormal growth of cells is called Cancer (which usually arises from an abnormal cell) in which cells lose normal control. Thus, a group of cells starts continuously growth, which attacks the surrounding tissue, which reaches the distant parts of the body and spread to other parts of the body through the lymph or blood. A cancer cell can develop in any tissue of the body.

As cancer cells grow and multiply manifold, they take the form of a group of cancer cells called tumors. These tumors attack nearby tissues and destroy them. Tumors can be cancerous or non-cancerous. The cancer cell can start from one place and spread to the whole body.

Beginning of Cancer-

The change in the genetic material of the cell begins with cancer. Changes in the cell's genetic material can be either by itself or by some agents or elements. These elements are Virus, Radiation, Smoking and Sunlight. But it is not necessary that all cells are affected equally with these agents. 

Growth of Cancer-

Some elements cause to grow in the development of cancer. These elements may also contain some substances such as sex hormone which is used to improve sexual desire. These elements themselves do not cause cancer - example, ionizing radiation - which is mostly used in X-rays) can cause various cancers, especially sarcoma, leukemia, thyroid cancer, and breast cancer.

How does cancer spread?

Scientists have found in research that damaged cells are attached to the healthy cells and continually follow them. Because of the associated with damaged cells, healthy cells come under their influence and the effect of cancer cells increases.

Types of cancer - 


1. Breast Cancer
2. Cervical cancer (cervical cancer)
3. Mouth cancer (oral cancer)
4. Prostate cancer (cancer of the prostate gland)
5. Uterine cancer (cervical cancer)
6. Ovarian Cancer (Ovarian Cancer)
7. Lung cancer (lung cancer)
8. Stomach cancer
9. Blood cancer (leukemia)
10. Bone Cancer (Bone Cancer)
11. Colorectal cancer (colon cancer)
12. Throat cancer
13. Liver cancer
14. Vaginal cancer
15. Skin cancer
16. Bladder Cancer
17. pancreatic cancer
18. Brain cancer (brain cancer)
19. Lymphoma
20. Kidney cancer (Kidney cancer)
21. Testicular cancers


Cancer Symptoms:

The sign of cancer does not appear when they use to be in small form. But as cancer progresses, its presence can affect the surrounding tissues. In addition, due to some cancer, some secretion of substances from the body starts to occur or some cancer triggers immune responses, which may cause symptoms of cancer in those parts of the body which are far away from the parts of the cancerous region.

Pain - Some cancers are painless before, but the initial symptom of some cancers can be painful, such as brain tumors, which lead to headache, and headache, neck, and anaphylaxis, in which there is pain during swallowing. As the cancer increases, its first symptom is often to feel uncomfortable, which can rapidly turn into severe pain with the spread of cancer. However, not all cancers cause severe pain. Similarly, the lack of pain does not guarantee that cancer is not spreading or spreading.

Bleeding - Few quantities of blood can come out in cancer. This bleeding may be minor and it can be diagnosed or not, it can be detected only with the test. This is the early stage of colon cancer. Bleeding, in the beginning, takes the cancer high, even this bleeding can be dangerous to health.

Blood clots - Some cancers produce the substances which cause the formation of blood in the body, mainly in the nerves of the legs. Blood clots in the nerves sometimes break down, which spread in the whole body, could be dangerous for you. Extra cloaking is common in people with pancreatic, lungs and other solid tumors, and people with brain tumors.

Weight loss and fatigue- Usually, the person with cancer experience weight loss and fatigue, which can further worsen this condition due to the increase in cancer. Some people have reported weight loss despite a good appetite. They can be very thin. People with advanced cancer often are very tired. 

Neurologic and muscular symptoms - Cancer can shrink the nervous system. It can be any of neurologic and muscular symptoms such as pain, weakness or change in cognition (such as tingling stimulation) etc. When cancer increases in the brain, it can be difficult to detect symptoms but it can lead to delusions, dizziness, headache, nausea, vision changes and seizures. 

Respiratory symptoms - Cancer can narrow or block structures such as airway in the lungs, which can lead to shortness of breath, cough or pneumonia etc. Breathing may also occur when cancer causes the pleural effusion between the lungs and chest, causing bleeding or anemia in the lungs.

Causes of Cancer –

There can be many reasons for causing Cancer. Many factors can increase the risk of developing cancer. According to each biology and pathology, each cancer is of a different kind. World Health Organization (WHO) says the following can be common factors for cancer:

1. Due to Heredity 
2. Age related factors
3. Environmental factors 
4. Unhealthy diet intake 
5. Increase in Medicines and Medical Treatment can increase Cancer Risk
6. Infections cause Cancer 
7. Inflammatory Disorders Are Due to Cancer Disease
8. One of the causes of cancer is poor Immunity system

Advice:

Many medicines are available for cancer. But, without consulting the doctor, please do not take any medicines. Non-prescribed medicine can be dangerous for health.
