What Causes Cancer – Key Factors
What Causes Cancer – Key Factors Cancer has many causes. These include genetic changes, things in our environment, and how we live. Each of these can help cancer grow.
Looking into cancer means studying these factors. We need to know how they work together. This helps us understand cancer better.
Introduction to Cancer
Learning about cancer starts with its cancer basics. This means understanding what it is. Cancer happens when cells grow out of control and can spread to other parts of the body.
There are over 100 types of cancer. These include breast, skin, lung, colon, prostate, and lymphoma. Each type forms in different parts of the body.
The importance of understanding cancer is huge. It helps us see how common it is and how it works. In 2021, the American Cancer Society said there would be almost 2 million new cases and 608,570 deaths in the U.S.
Cancer happens because of DNA changes in cells. DNA tells cells how to grow. But when it changes, cells can grow too much and spread.

Genetic Mutations and Cancer
Genetic mutations are key in cancer’s start. They change DNA, causing cells to grow out of control. This can lead to tumors. Knowing about these changes helps us understand cancer better.
Oncogenes
Oncogenes are bad versions of normal genes. They make cells grow too much. This is a big sign of cancer. Finding ways to stop these genes is important for fighting cancer.
Tumor Suppressor Genes
Tumor suppressor genes keep us safe from cancer. They help cells grow right and fix DNA mistakes. If these genes stop working, cancer can start more easily. Scientists work to fix these genes to help our bodies fight cancer.
Inherited Mutations
Some cancers run in families because of genetic mutations. These changes can make people more likely to get cancer. Finding these mutations helps doctors find ways to prevent and catch cancer early.
| Genetic Aspect | Description | Impact on Cancer |
|---|---|---|
| Oncogenes | Mutated proto-oncogenes that cause uncontrolled cell division | Leads to tumor development and cancer progression |
| Tumor Suppressor Genes | Genes that regulate cell growth and repair DNA | If inactive, increases the risk of cancer |
| Inherited Mutations | Mutations passed down through families | Elevates individual cancer risk |
Learning about genetic mutations helps us fight cancer. By understanding oncogenes, tumor suppressor genes, and inherited risk, we can improve cancer treatment and prevention.
Environmental Factors
Cancer can be caused by many things in our environment. This includes radiation, chemicals, and pollution. Knowing about these helps us stay healthy and safe.
Exposure to Radiation
Radiation is a big risk for cancer. It can come from X-rays, the sun, and more. We should use less X-rays and protect our skin from the sun.
Chemical Carcinogens
Chemicals around us can also cause cancer. Things like tobacco smoke and chemicals in products are dangers. Knowing what these chemicals are helps us avoid them.
Pollution and Cancer
Pollution in the air and water can also lead to cancer. It’s important to clean up pollution. This helps keep us safe from harmful substances.
Lifestyle Choices and Cancer Risk
Knowing how our lifestyle choices affect cancer risk is key to staying healthy. This part talks about how diet, exercise, and smoking can change our cancer risk.
Diet and Nutrition
Eating right is crucial for cancer prevention. Eating lots of fruits, veggies, whole grains, and lean meats can help. But, eating too much processed food, red meat, and sugar can increase cancer risk.
Choosing healthy foods can greatly lower your cancer risk.
Physical Activity
Staying active is also vital for cancer prevention. Exercise helps keep you healthy, boosts your immune system, and lowers inflammation. This can help prevent cancers like breast, colon, and endometrial cancer.
So, making exercise a part of your daily life is important.
Smoking and Tobacco Use
Smoking and tobacco use are big cancer risks. Tobacco’s harmful chemicals can cause cancer. Lung cancer is a big risk from smoking, but it can also cause other cancers.
Not smoking is a big step to lower your cancer risk.
In short, making smart choices about diet, staying active, and not smoking can greatly reduce your cancer risk. These steps are key to keeping you healthy and fighting cancer.
What Causes Cancer
Cancer is a complex disease. It comes from many factors that mess up cell functions. Knowing what causes cancer means looking at many things that disrupt cells.
Genetic mutations are key in cancer etiology. These changes happen in two types of genes: oncogenes and tumor suppressor genes. When these genes mutate, cells grow too much and form tumors. Some of these changes are passed down from parents, making some people more likely to get cancer.
Extrinsic factors, or cancer risk factors, include things we can control. Things like radiation, chemicals, and pollution can harm DNA and cause cancer. Also, choices like smoking, eating badly, and not moving enough can increase cancer risk.
The mix of these factors leads to cancer. By understanding cancer risk factors, experts can work on preventing and treating it. This helps fight cancer worldwide.
Viral and Bacterial Infections
Viral and bacterial infections can cause cancer. They do this by causing long-term inflammation and genetic changes. This leads to cancer in cells. We will look at three main infections that cause different cancers.
Human Papillomavirus (HPV)
HPV is known to cause cervical cancer. It also causes anal and oropharyngeal cancers. The virus stays in the body and causes cell changes that can lead to cancer.
Hepatitis B and C
Hepatitis B and C infections are linked to liver cancer. These viruses cause long-term inflammation in the liver. This can lead to cirrhosis and liver cancer.
Helicobacter pylori
Research shows a link between Helicobacter pylori and stomach cancer. This bacterium causes long-term inflammation in the stomach. It can lead to stomach lining changes that may become cancerous. Treating Helicobacter pylori can lower the risk of stomach cancer.
Hormonal Factors
Hormones play a big role in cancer. They help some cancers grow. Estrogen is especially important in this area.
Estrogen and Cancer
Estrogen is key in breast cancer. Too much estrogen can lead to breast cancer. It makes cells grow too much.
Estrogen also affects ovarian and endometrial cancers. This shows how important it is to watch hormone levels. Especially for those with a family history of cancer.
Hormone Replacement Therapy
Hormone replacement therapy (HRT) helps with menopause symptoms. But, it can raise cancer risks. This is especially true for breast cancer.
The type, how long, and how much HRT you take matters. It’s important to talk to your doctor before starting. This helps make sure it’s safe and works well.
Age and Cancer Risk
The link between aging and cancer is a big topic in oncology. As people get older, they are more likely to get cancer. This is because their genes change over time and their immune system gets weaker.
Older people get cancer more often. This shows how important it is to understand why. As we age, our cells get mutations that can cause tumors. Also, older people’s immune systems can’t fight off bad cells as well.
Studies show that aging and cancer are closely connected. Cancers like breast, prostate, and colon cancer get more common with age. Older people also have more health problems, making cancer harder to treat.
It’s key to understand how aging and cancer are linked. This helps doctors find better ways to prevent and treat cancer in older people. By focusing on the needs of older cancer patients, doctors can help them live better lives.
In short, aging and cancer are closely related. We need more research and special care for older adults with cancer. This will help tackle the growing problem of cancer in the elderly.

Preventative Measures
Knowing how to prevent cancer is key. A healthy lifestyle is a big part of it. Eat lots of fruits, veggies, and whole grains. Avoid processed foods, red meats, and too much fat.
Being active is also important. It helps keep you at a healthy weight. This is good for lowering cancer risk.
Vaccines are another big help. Shots like the HPV and Hepatitis B vaccines can stop some cancers. Getting these shots can really cut down your cancer risk.
Screenings are also very important. Tests like mammograms and colonoscopies can find cancer early. This means you can get treated sooner.
It’s smart to talk to your doctor about screenings. They can help you figure out when you need them. This way, you can catch cancer early and treat it better.
By making healthy choices, getting vaccinated, and getting screened, you can fight cancer. This helps you stay healthy and helps everyone else too. It’s all about being proactive and taking care of yourself.
