Identifying and treating a disease early increases the chances of survival. This is particularly true for certain cancers, such as the breast, cervix, and colon.

Implementing cancer prevention strategies requires a concerted effort by governments, healthcare providers, community groups, and individuals. It also depends on a cultural belief that individual choices have important effects on long-term health.

Symptoms

Symptoms are changes you feel or see in your body. Cancer can cause many different signs and symptoms. A few of them can signal that you need to see a doctor and check your health.

Getting diagnosed and treated early can make treatment much easier when the cancer is small and hasn’t spread. It can also help you better survive the disease and live a longer, healthier life.

There are many ways to spot cancer’s early signs and symptoms, such as checkups, screening tests, and genetic testing. Ask your doctor about the right test based on age, risk factors, and family history.

Some of the most common symptoms include unusual bleeding, pain or discomfort, a change in bowel habits, and weight loss. Blood in your stool or a discharge from your nipples can be signs of breast cancer, and abnormal vaginal bleeding may be an early sign of ovarian or endometrial cancer.

Another important symptom is fatigue or weakness. This can indicate that you’re not getting enough energy from food or that cancer has attacked your immune system.

It can also be a sign that cancer has spread to other parts of your body. This is known as metastasizing.

Other symptoms that may signal a problem include sores that don’t heal, coughing or hoarseness that doesn’t go away, and swelling. Some of these symptoms are common for many different conditions, but it’s important to let your doctor know about any new ones you have and keep them under control if they don’t get better.

During the physical exam, your doctor will look for changes in your skin or organs, such as your lungs or lymph nodes. Your doctor may also use a special instrument called a CT scan to find out more about what’s going on with your body.

Your doctor will then perform lab tests to see what’s happening with your cells. These lab tests can show that normal cells are uniform and look similar, whereas cancer cells are disorganized and don’t have a uniform shape. These findings can help your doctor diagnose your cancer and determine its stage, which enables you to understand the type of treatment and your chances of a cure.

Risk factors

Cancer risk factors are conditions that increase your chance of getting a certain kind of cancer. They include your gender, age, race, and what you do to make yourself healthier. It is important to know your risk factors so you can talk with your doctor about them.

Some risk factors can be inherited from your parents, but others are not. Hereditary factors are often related to specific gene defects that can increase cancer risk. For example, women with a gene mutation called BRCA1 have a lifetime risk of up to 70 percent for breast and ovarian cancer. These types of genes are rare in the general population, but they can affect people in certain families.

Genetic testing can help determine your cancer risk if you have a high-risk gene. The information you get from a test can help you and your doctor decide whether or not to get more tests.

For example, a doctor may recommend a colonoscopy when you’re at high risk for colon cancer. This can help you find cancer early and lower your chance.

Lifestyle and genetic risks can also increase your chances of getting cancer. To lower your cancer risk, you can eat a healthy diet, exercise regularly, and avoid smoking and other tobacco use. You can also get some vaccines to reduce your cancer risk.

However, some risk factors can be caused by your environment, such as cigarette smoke or chemicals in your home. If you want to avoid these risk factors, discuss ways to reduce them with your doctor.

Other risk factors are things you do, such as having a family history of cancer or taking a certain medication. You can talk with your doctor about these risk factors to see if they are something you can do to lower your cancer risk.

As the number of risk factors for cancer grows, it is essential to develop a system to assess them and integrate them into screening programs. This is particularly important for risk-adjusted screening. A screening program will only be successful if it is tailored to the specific risk profile of individual patients. Hence, it needs to consider each person’s biological and environmental risk factors.

Screening

Detecting cancer before symptoms develop can help reduce the risk of developing it and reduce the need for treatment. When cancer is discovered too late, it can be harder to treat, and a person’s chance of survival is lower.

Screening tests include blood, urine, or tissue samples; genetic tests that look for changes in your genes linked to certain types of cancer; and imaging procedures such as mammograms and colonoscopies. These tests can help doctors find cancers and other diseases that might not have symptoms but that could cause serious problems if left untreated.

The most common type of screening is population-based, in which an entire group of people is screened. This approach has been proven effective for cervical and colorectal cancers, reducing the number of new cases diagnosed and deaths due to these cancers.

However, it is important to remember that not all cancers can be found through screening. Sometimes, a test may miss cancer, so it is still important to talk with your doctor about any problems you are having, even if you have had a screening test recently.

Another problem with screening is that it can sometimes give you abnormal results when you do not have cancer (a ‘false-positive’ mark). This can make you worry, cause you to delay seeing your doctor, and result in more tests that have side effects.

It is also possible for screening to overdiagnose or overtreatment of a person’s cancer. This can be especially problematic for latent cancers of uncertain clinical significance, as autopsy studies have shown over the decades.

Ultimately, weighing the benefits of screening against the harms of treatment is crucial, and this is not easy. This is especially true for conditions with a short preclinical period, such as breast, endometrial, and latent cancers, that are not destined to progress or affect the patient’s health.

Researchers control observational studies and other kinds of research to determine whether a screening test is helpful. These can compare the outcomes of people who do and don’t get screened and bring investigators one step closer to definitive evidence.

Prevention

Prevention involves reducing or eliminating risk factors that lead to cancer. This may include changing your diet and lifestyle, smoking cessation, and screening tests. It also detects cancer early, when it’s smaller and easier to treat.

Research shows that if you detect cancer early, it’s more likely to be treated successfully. For example, in England, more than 9 in 10 bowel cancer patients survive their disease for 5 years or more if diagnosed at an early stage.

The most effective preventive approaches have a strong public health orientation and involve interventions that target entire populations. However, this is often difficult to achieve. In addition, the results of a screening program often depend on individual behaviors, which tend to vary among different populations.

For example, the impact of cervical Pap smear screening on preventing cervical cancer varies widely between countries. It’s unclear if this is because of differences in the incidence of cervical cancer or the effectiveness of the screening methods used.

It’s important to remember that a large proportion of cancer mortality can be prevented by simple, largely unobtrusive changes in behavior or lifestyle. Such changes include increasing physical activity, avoiding sedentary activities, and improving the diet.

Positive effects often accompany these changes in other aspects of health such as mental well-being, quality of life, and physical and mental function. Moreover, they can lower health care costs and increase patient satisfaction.

Many community-based prevention programs are helping to decrease the rate of cancer in Australia. The National Cancer Control Program (NCCCP) supports some of these programs. These programs provide evidence-based information and tools for people to make healthy choices.

The NCCCP works with state and local governments, cancer societies, medical providers, and other community groups to develop and implement cancer prevention programs. These programs reduce cancer risk, save lives, and improve the quality of life for all affected by cancer.

The DF/HCC Cancer Risk, Prevention, and Early Detection program focuses on understanding how a person’s genetics, environment, and lifestyle influence cancer development. It also aims to translate these discoveries into novel paradigms for cancer interception and to develop and test new technologies and practices for prevention.
