Cancer is a word that strikes fear in anyone, but understanding what it is can make it less mysterious and more manageable. Cancer is a group of diseases at its core where the body’s cells divide and grow abnormally. Normally, our cells divide and grow in a very orderly way. When cells divide and develop, they die, and new cells form. When the cellular machinery is hampered, it leads to the formation of cancerous outgrowths, which, when spread, can also be life-threatening and may lead to death.At its simplest, cancer is a disease where some of our body’s cells divide uncontrollably and spread to other body parts. However, the reality of cancer is much more complex, involving the interaction of genetics, environment, and lifestyle factors. In this article, we will provide a guide about the cancer types, their basics, and their overall impact on a person.
What is something called cancer?
As all types of Cancer arise from the abnormal growth of the cell, leading to the formation of a mass called a tumor, here are some of the features that contribute to cancer development in the body:-
Gene mutation- Any kind of error in DNA can cause our cells to lose their normal functioning and lead to uncontrolled division. Some of it can also pass from parents to their offspring (Inherited mutation), while others may happen later in life(Acquired mutation)
Uncontrolled Cell Division- Unlike normal cells, which die and are replaced by new ones, Cancerous cells keep on dividing, forming a cancerous mass or tumor growth. masses also crowd off the normal cells.
Cancer Spread(Metastasis)—Unlike a tumor, a cancer cell can spread to other parts of the body, invade other tissues, and worsen the situation if not treated on time.
What should be called cancer?
Not all cell mass and outgrowth is considered cancer, for example
Tumors- These are lumps or masses that can be malignant(cancerous) or benign(non-cancerous)
Precancers- These are abnormal cells that can become cancerous over time
Cyst- These are the sac-like outgrowths that can be filled with pus, mucus, or tissue. Most cysts do not contain abnormal cells and are not cancerous.
What are the Early Signs and Symptoms associated with Cancer?
Unexplained Weight Loss- Losing weight without any reason could be a sign of cancers like stomach, lung, or pancreatic cancer.
Persistent Fatigue- Extreme tiredness that doesn’t improve with rest may signal leukemia or other cancers.
Lump or Thickening- A new lump in the breast, testicle, or elsewhere can be an early warning sign.
Changes in the Skin- Dark spots, yellowing skin (jaundice), or redness.
Persistent Cough or Hoarseness- A cough that doesn’t go away or changes in your voice could indicate lung, throat, or thyroid cancer.
Unusual Bleeding or Discharge- Blood in urine, stool, or when coughing, as well as unusual vaginal bleeding may indicates cancer, should be checked immediately.
Difficulty Swallowing- Trouble swallowing may point to throat or esophageal cancer.
Persistent Pain-Chronic pain, such as back pain, may be linked to cancers of the bones or other organs.
Changes in Bowel or Bladder Habits-Long-term constipation, diarrhea, or changes in stool size may indicate colon cancer.
Sores that Do Not Heal- A sore on the skin or in the mouth that doesn’t heal could be a warning sign of skin or oral cancer.
White Patches Inside the Mouth or on the Tongue- Known as leukoplakia, this can be a pre-cancerous condition often associated with tobacco use.
Discomfort After Eating- Could signal stomach, esophageal, or throat cancer.
Lumps in the Lymph Nodes- Especially in the neck, armpits, or groin area.
Changes in Breast Appearance- Apart from lumps, look for changes in size, shape, dimpling, or nipple discharge that could indicate breast cancer.
Night Sweats- Heavy night sweats, especially if accompanied by weight loss or fatigue, can be a symptom of lymphoma.
What are the Causes of Cancer?
Cancer is usually caused by a combination of genetic and environmental factors. Here are some of the causes-
Genetic mutations: Some people inherit mutations that increase their chances of developing certain cancers. For example, mutations in the BRCA1 and BRCA2 genes increase the risk of breast and ovarian cancer.
Environmental exposures: Certain chemicals, such as those found in tobacco smoke, can cause mutations. Exposure to harmful radiation, like ultraviolet (UV) rays from the sun, is also a significant risk factor.
Lifestyle factors: Diet, physical activity, alcohol consumption, and tobacco use all play roles in increasing or decreasing cancer risk.
Infections: Certain viruses and bacteria can also lead to cancer. For example, human papillomavirus (HPV) can cause cervical cancer, and Helicobacter pylori infections are somewhat linked to stomach cancer.
Note– it’s important to remember that cancer can happen to anyone, and sometimes it occurs without any known risk factors.
What are the two main types of cancer?
Cancers can be divided into two categories
Blood cancer- It starts in the blood cells or tissue, ex,
Leukemias (cancers of the blood and bone marrow)
Lymphomas (cancer of the immune system cells)
Solid Cancer- starts forming in tissue and bones, some common types include
Carcinomas (the most common type, starting in the skin or tissues that line internal organs)
Sarcomas (begin in the bones, muscles, fat, or connective tissues).
Brain and spinal cord cancers (known as central nervous system cancers)
How Cancer Spreads?
Metastasis is the process by which cancer cells move from the original site to other parts of the body. This makes cancer much harder to treat. Cancer cells can slough off, (break away) from a tumor, travel and spread through the bloodstream or lymph system, and form new tumors in other organs.
When cancer spreads, it is still named after the place where it started. For example, if breast cancer spreads to the lungs, it is still called breast cancer, not lung cancer.
Understanding metastasis is crucial because the treatment strategy often changes once cancer has spread.
How to Diagnose Cancer?
Early diagnosis of cancer can help stop its spread in the very early stage. Some of the methods of early detection are
Screening tests: Such as mammograms for breast cancer, colonoscopies for colon cancer, and Pap tests for cervical cancer.
Physical examinations: Checking for lumps or changes in the skin.
Genetic testing- Recommended for individuals with a strong family history of certain cancers.
What are the treatments for Cancer?
Cancer treatment has evolved enormously over the past few decades. The main types of treatment include:
Surgery: Removing cancerous tissue from the body.
Radiation therapy: Using high-energy rays to kill or shrink the tumor.
Chemotherapy: It is a traditional way that uses drugs to kill fast-growing cells, including cancer cells.
Immunotherapy: Enhances the immune system to recognize and attack cancer cells specifically without harming normal cells.
Targeted therapy: Attacking specific genes or proteins that are involved in cancer growth.
Hormone therapy: Blocking hormones that help certain cancers to spread, such as breast and prostate cancer.
Stem cell transplants: Often used for blood-related cancers like leukemia.
How to Prevent Cancer?
Here are some of the preventive measures you can take to reduce the risk of cancer-
Avoid tobacco
Eat a healthy, nutritious diet rich in fruits, vegetables, and whole grains.
Maintain a healthy body weight and stay physically active.
Protect yourself from the sun by wearing sunscreen and avoiding tanning beds.
Get vaccinated against cancer-causing infections, such as HPV and Hepatitis B.
Practice safe behaviors to avoid infections that can lead to cancer.
If you are an older adult or a senior citizen, you must go for routine screening tests for cancer
Advances in Cancer Care
Ongoing research and Clinical trials in cancer biology, genetics help revolutionize cancer treatment with the introduction of Personalized plans and medicine, where treatments are specific to the individual genetic profile of both the patient and the tumor, is becoming more common.Advanced cell therapies, such as Dendritic Cell-based therapy and CAR T-cell therapy, which modify a patient’s immune cells to attack cancer specifically without harming normal cells, offer hope where little existed before. Scientists are also exploring the role of the microbiome (the bacteria living inside our bodies) in cancer development and treatment.While challenges remain, the future holds promise for better prevention, earlier detection, more effective treatments, and, ultimately, cures.
Final thought
Cancer is a complex and fearful disease that can raise multiple questions in our minds about how it is caused, its early signs and symptoms, diagnosis, and treatment. Understanding its basics helps you to clear your concepts and fears regarding this disease. Knowledge empowers us to take preventive steps to recognize early warning signs and to seek effective treatment when necessary.As research advances and treatments improve, there is more hope than ever for people facing cancer. If you are living with cancer, if you have any persistent symptoms must consult a doctor and find a top immunotherapy centre that can help you understand and guide you about the condition more effectively.
