1. Introduction to cancer

 

    Cancer is a group of diseases that make you lose your hair, cause other parts of your body to swell, and spread throughout your body. There are many types of cancer and each will affect different parts of your body differently.

Compared to other forms of cancer, smoking and tobacco use is the leading cause of cancer in the United States. In fact, according to the Centers for Disease Control and Prevention (CDC), more than half of all deaths caused by smoking are due to cigarette smoking.

Smoking is also linked to other cancers such as lung cancer and heart disease. The average person who smokes 200 cigarettes or more a day will experience about 2,850 heart attacks or strokes. For every 100 people who smoke at least one cigarette a day, there will be 28 cases of lung cancer and 13 cases of bladder cancer before age 65.

Tobacco use has also been linked with several types of cancers such as esophageal, stomach, liver, prostate, pancreas, and colon (cancer is not only found where we look). Cancer can also be caused by exposure to certain viruses such as human papillomavirus (HPV), which can lead to cervical cancer or anus cancer. Exposure to tobacco smoke can also cause an illness called pulmonary hypertension or pulmonary hypertension-related end-stage lung disease (Pulmonary hypertension is a medical condition that occurs when there is not enough blood flow in the lungs).

Another type of cancer caused by radiation exposure includes malignant melanoma (a malignant tumor that causes skin tumors). A second type is called malignant breast tumor; this type tends to occur in women older than 50 years old with no family history of breast cancer. Other cancers include liver cancers from hepatitis B infection and from alcohol abuse; respiratory cancers from cigarette smoking; bladder cancers from marijuana use; colon cancers from excessive alcohol usage; kidney cancers from diabetes mellitus type 1 or type 2 diabetes; thyroid cancers from radioactive iodine treatment for thyroid disorders; rheumatoid arthritis; soft tissue sarcomas including osteosarcomas and myoclonus tremors; lymphomas including Hodgkin’s lymphoma but not non-Hodgkin’s lymphomas which occur usually in children younger than 15 years old although they may occur in adults as well.)

 

2. What are carcinogens?

 


In 2011, the World Health Organization (WHO) published a report called “Cancer Facts and Figures” to help people better understand the medical condition and treatment of cancer. The report stated that there are many different types of cancer and that they all have different causes. In general, cancer is a disease where cells change in size or become abnormal as a result of abnormal growth. This abnormal growth can come from one of several different causes, such as:

3. What are some known causes of cancer?

 

Cancer is the name for a group of multifactorial diseases that originate in the body and spread through the bloodstream to different parts of the body. The cause of cancer can either be genetic in origin or it can be caused by environmental factors. Cancer is also sometimes referred to as malignant neoplasm or neoplasmic growths (also known as tumors).

Many forms of cancer usually develop over time and may consist of different types such as epithelial, mesenchymal, lymphatic (or leukemia), and teratomas (tumors). Commonly recognized types are:

Epithelial cancers such as lung cancer, breast cancer, prostate cancer, colorectal cancers, brain tumors, mouth and throat cancers, cervix, colon, rectum, skin tumors, liver tumors. Mesenchymal cells are derived from embryonic stem cells (which are found in embryos) or other types of adult cells including fibroblasts and osteoblasts. These cells contribute to forming various tissues including muscle, bones, nerves, and blood vessels. Lymphatic tissues can include blood vessels or lymph nodes. Prostate gland cancers resemble tissue formed by fibroblasts in that they arise from adult cells but they do not undergo apoptosis; i.e., they aren’t destroyed by apoptosis. In fact, they are mature cell structures with limited life span like normal tissue but without apoptosis; i.e., they remain alive indefinitely like normal tissue but without apoptosis; i.e., they aren’t destroyed by apoptosis; i.e., they stay alive indefinitely like normal tissue but without apoptosis; i.e., no stage-3 diseases involving apoptosis). Leukemia is an active form of acute leukemia with abnormal cell division and uncontrolled proliferation that develops from multiple abnormal leukocytes (white blood cells) within the bloodstream due to a lack of oxygen-carrying red blood cells

The most commonly recognized carcinogen in cigarette smoke is because it contains thousands of chemicals called free radicals which damage DNA by breaking up its structure. Long term exposure to these free radicals leads to damage to DNA which results in mutations (break-ups) of chromosomes even though it isn’t

 

4. What about possible causes of cancer?

 

We all know that smoking cigarettes leads to various health problems, including cancer. But four out of every five people who become smokers also smoke tobacco, which is a harmful substance. This is not an isolated case. Most people don’t realize that eating unripe fruits and vegetables can cause cancer, too.

As of 2015, the World Health Organization (WHO) has identified more than 300 known carcinogens in different types of plant and animal products, including tobacco and processed meat. These are the substances that are believed to cause the development of cancer in humans. Most of them are natural chemicals found in plants or animals. In fact, many plants contain other chemicals that can lead to cancer.

Smoking or chewing tobacco is one of the most common known causes of cancer worldwide, as it is one of the most common causes of lung cancer as well as oral and pharyngeal cancers. The WHO estimates that more than 480 million people worldwide die from tobacco-related diseases every year. This number does not include all those who have died from other forms of smoking-related diseases like heart disease and stroke. And about 715 million people currently live with lung cancer [1].

Roughly 715 million people live with lung cancer around the world [2]. Cancer is caused by abnormal cells growing in our bodies, especially within our lungs and other parts of our bodies where air circulates [3]. Some cancers are inherited or passed on through family members; some develop over a long period, while others appear suddenly; some are treatable but may go into remission after a few years; some do not respond to proper treatment or surgery, and some can be cured by following certain lifestyle guidelines and medications [4].

The most common way we acquire cigarette smoke-related health problems is by inhaling it into our lungs when we smoke cigarettes or when we cough or sneeze while we are smoking them [5]. We breathe out a lot of these harmful substances called carcinogens while breathing out smoking cigarettes: carbon monoxide (CO), nicotine (the addictive nicotine component), arsenic (the poisonous poison arsenic), carbon dioxide (a gas produced when living organisms die) and hydrogen cyanide (a poisonous gas produced during rotting flesh [6]). Carbon monoxide has been linked to lung cancer among smokers because it gets into your bloodstream through your lungs [7]. That’s why it’s important for you to stop smoking cigarettes before you start going breathless with coughing

 

5. How do genes play a role in cancer?

 


In this section, you will learn more about the causes of cancer. You will also learn about the different types of cancer and how it may develop in different areas of the body. In addition to learning about the causes of cancer, you will also learn about how genes play a role in cancer.

 

6. Conclusion - Now you know more about cancer, and how it is caused by both environmental factors and your

 

Cancer is a complex group of diseases that have many causes. In this section, you can learn more about the known and possible causes of cancer and general information about carcinogens, and how genes play a role in cancer.

There are many reasons why people develop cancer. Sometimes it’s because of an environmental factor (like smoking) or because of a genetic mutation. Sometimes it’s caused by something you did once or twice in your life (like being exposed to chemicals). Sometimes it’s caused by poor lifestyle choices (such as smoking cigarettes or drinking alcohol).

Sometimes it happens because something made up inside your body went wrong. The exact cause may be unknown at this point – but there are several things we do know:

Some types of cancers: Colorectal Cancer Breast Cancer Thyroid Cancer Leukemia Kidney Cancer CNS tumors Bladder Cancer Pancreatic Cancer Colon & Rectal Cancer Prostate Cancer Brain Tumors Skin Tumors Brain & Headaches Mouth & Throat Tumor Lung Tumor Eye Tumors Bladder Tumour Skin Tumor Gall Bladder Gall Bladder Pancreas Stomach Stomach Stomach Oesophagus Gall Bladder Pancreas Liver Liver Liver Pancreas Pancreas Colon & Rectal Colon & Rectal Colon & Rectal Adrenal Glands
