As we delve into the topic of cancer, we often overlook some of the most fundamental questions that could provide us with a better understanding of the disease.
In this article, we aim to address 10 common and critical questions that people often have about cancer.
Despite the vast amount of information available on cancer, there are still many misconceptions and unanswered questions.
Throughout this article, we will provide clear and concise answers to these frequently asked questions, covering various topics from different cancer types, such as breast, pancreatic, lung, and skin cancer, to a basic understanding of what cancer is.
1. Who is at risk for cancer?
Cancer can affect anyone, but the likelihood of developing it increases with age. Various factors can influence an individual’s risk, including smoking, lifestyle choices such as diet and exercise, family history of cancer, and workplace and environmental factors. Avoiding risk factors like tobacco, excessive alcohol consumption, and obesity can help reduce cancer risk.
2. How Cancer Begins
Our body comprises various types of cells, which usually grow, divide, age, and die. However, sometimes, these cells mutate and grow uncontrollably, forming a mass or tumor instead of dying. Tumors can either be benign or malignant. Benign tumors are noncancerous and do not pose a significant threat to our body, while malignant tumors are cancerous and can damage and kill our body’s tissues.
Malignant tumors can also spread to other parts of the body, causing new tumors to form there. This process is called metastasis and indicates that cancer has advanced to a late stage. The causes of cancer can be radiation, chemicals, or other factors that can damage our DNA.
3. Is Cancer Genetic?
Cancer is caused by mutations or gene changes that control how our cells function. These mutations can be inherited in about 5-10% of all cancer cases, but most gene changes occur during a person’s lifetime due to other factors besides genetics.
However, when someone has a known family history of hereditary cancer, genetic testing is often recommended to identify genetic mutations that increase the risk of developing cancer. Hormones and other environmental factors can also play a role in cancer development, but genetics is a significant factor in many cases.
4. Is cancer contagious?
No, cancer is not contagious. It is not like the flu or a cold and cannot be caught by someone with the disease. There is no evidence to suggest that viruses like human papillomavirus (HPV) or hepatitis B can be transmitted from person to person through cancer.
5. Is there a vaccine for cancer?
Currently, there is no vaccine for cancer. However, vaccines are available to prevent viruses that can lead to cancer, such as the human papillomavirus (HPV) and hepatitis B. HPV can cause several types of cancer, including cervical, anal, throat, and penile cancers. The HPV vaccine can protect against many virus strains that can cause these cancers.
Similarly, hepatitis B has been linked to liver cancer, and the hepatitis B vaccine can reduce the risk of developing liver cancer by protecting against the virus that might lead to it.
It is important to note that these vaccines do not protect against cancer itself but rather against the viruses that can cause it. Other ways to reduce the risk of developing cancer include maintaining a healthy weight, exercising regularly, and following a healthy diet. While a vaccine for cancer may not yet be available, taking proactive steps toward cancer prevention can help protect against the disease.
6. Can cancer be cured?
When cancer treatment is successful, doctors may declare that the cancer is in remission. A partial remission occurs when the cancer shrinks but doesn’t disappear. A complete remission means there is no sign of cancer. The longer the cancer remains in complete remission, the less likely it is to return. Eventually, doctors may declare that the cancer has been cured.
However, it is essential to note that not all cancers can be cured, and treatment success depends on the type and stage.
7. What are the stages of cancer, and what do they mean?
Cancer is typically classified into four stages: I through IV, with some cancers having a stage 0. The stages indicate the severity of the cancer and how far it has spread.
Stage 0 is the earliest stage, where the cancer is still localized and hasn’t spread to nearby tissues. This stage is often curable with appropriate treatment.
Stage I represents a small tumor or cancer that hasn’t grown deeply into nearby tissues. It’s sometimes referred to as early-stage cancer.
Stages II and III represent more significant cancers or tumors that have grown more deeply into nearby tissues. They may have also spread to nearby lymph nodes but haven’t affected other organs or parts of the body.
Stage IV is the most advanced stage, where cancer has spread to other organs or parts of the body. This stage is also known as metastatic or advanced cancer.
The cancer stage is determined by staging, which involves various tests and examinations to assess the extent of the cancer’s spread. The stage of cancer plays a crucial role in determining the appropriate treatment plan and prognosis for the patient.
8. Does cancer have symptoms?
Cancer may or may not have symptoms, depending on where it is located and how big it is. The signs and symptoms of cancer can vary from person to person. Some cancers grow in places where they won’t cause any signs or symptoms until they have advanced.
For example, pancreatic cancer usually doesn’t cause any signs or symptoms until it grows large enough to press on other structures, causing pain or manifesting signs of jaundice, which is yellowing of the skin.
However, some general signs and symptoms of cancer can include unexplained weight loss, fever, fatigue, pain, skin changes, bowel habit or bladder function changes, sores that don’t heal, unusual bleeding or discharge, a thickening or lump in a part of the body, such as a breast, indigestion or trouble swallowing, a recent change in a wart or mole, and a nagging cough or hoarseness.
It is important to remember that there can be other reasons for these signs and symptoms. The only way to find out what’s causing them is to see your doctor. If you notice any of these symptoms that don’t pass, it is time to examine them.
9. How Do Cancer Drugs Work?
Chemotherapy drugs are used to destroy cancer cells, but they can also harm healthy cells, leading to treatment side effects. Targeted drugs, on the other hand, block genes or proteins found in the cancer cells and usually cause less harm to healthy cells.
However, targeted therapy still has side effects. Immunotherapy uses hormones and other drugs that work with our immune system to treat cancer. Clinical trials are conducted to test the effectiveness and safety of these drugs.
10. When to Consider Cancer Screening
Recommendations for cancer screening tests and the age at which they should be done vary based on the type of cancer. It is essential to consult with your doctor to determine which tests are necessary and when. Here are some general screening guidelines for five common cancers:
| Cancer Type | Screening Test | Age to Begin Screening |
|---|---|---|
| Breast | Mammogram | 50 |
| Cervical | Pap Test | 21 |
| Colorectal | Stool Test or Colonoscopy | 45 |
| Lung | Low-Dose CT Scan | 50 |
| Prostate | PSA Blood Test | 50 |
Remember that these guidelines are general; your doctor may recommend different screening tests based on your health history and risk factors.
Turn to the experts.
It’s essential to seek advice from doctors and specialists regarding cancer care. Speak to your Primary Care Physician if you are experiencing any strange symptoms. It is highly recommended that you schedule an annual physical check-up and blood work. These routine examinations can provide valuable insights into your overall health and help detect any underlying issues at an early stage. Taking proactive steps towards your well-being is crucial for maintaining a healthy and balanced lifestyle. -T
