🧬 What Is Cancer?
Read In English / हिन्दी में पढ़ें
Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death. Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place. Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue. Tumors can be cancerous (malignant) or not cancerous (benign). (Ruesch Center for GI Cancers, Cancer Info and Resources)
🧾 What Causes Cancer?
Cancer is caused by changes (mutations) to the DNA within cells. These mutations can be inherited or acquired due to environmental exposures. Common causes include:(Cleveland Clinic)
- Lifestyle factors: Smoking, excessive alcohol consumption, poor diet, lack of physical activity, and obesity.
- Environmental exposures: Exposure to certain chemicals, radiation, and ultraviolet rays from the sun.
- Infections: Certain viruses and bacteria can increase the risk of cancer. (Cancer Research UK)
🧪 How Is Cancer Diagnosed?
Cancer diagnosis typically involves a combination of methods:
- Medical history and physical exam: Assessing symptoms and risk factors.
- Laboratory tests: Blood, urine, or other tests to look for abnormalities.
- Imaging tests: X-rays, CT scans, MRI, PET scans to detect tumors.
- Biopsy: Removing a sample of tissue to examine under a microscope.(Stanford Health Care, Life Imaging FLA)
🧬 What Are the Types of Cancer?
There are over 100 types of cancer, commonly categorized by the organ or tissue where they originate. Some major types include:
- Carcinoma: Cancer that begins in the skin or in tissues that line or cover internal organs.
- Sarcoma: Cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue.
- Leukemia: Cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the bloodstream.
- Lymphoma and myeloma: Cancers that begin in the cells of the immune system.
- Central nervous system cancers: Cancers that begin in the tissues of the brain and spinal cord.(Ruesch Center for GI Cancers)
A comprehensive list of cancer types can be found at the National Cancer Institute: (Comprehensive Cancer Information)
🛡️ How Can Cancer Be Prevented?
While not all cancers are preventable, certain measures can significantly reduce risk:
- Avoid tobacco: Smoking is linked to various types of cancer.
- Healthy diet: Consuming a diet rich in fruits, vegetables, and whole grains.
- Regular exercise: Maintaining a healthy weight and staying active.
- Limit alcohol: Reducing alcohol intake can lower cancer risk.
- Sun protection: Using sunscreen and avoiding excessive sun exposure.
- Vaccinations: Vaccines like HPV and Hepatitis B can prevent certain cancers.
- Regular screenings: Early detection through screenings can catch cancers early when treatment is more effective.
💊 What Are the Treatment Options for Cancer?
Cancer treatment depends on the type and stage of cancer and may involve one or more of the following:
- Surgery: Removing the cancerous tumor.
- Radiation therapy: Using high-energy rays to kill cancer cells.
- Chemotherapy: Using drugs to kill cancer cells.
- Immunotherapy: Helping the immune system fight cancer.
- Targeted therapy: Targeting specific molecules involved in cancer growth.
- Hormone therapy: Blocking hormones that fuel certain cancers.
- Stem cell transplant: Restoring blood-forming stem cells in patients who have had theirs destroyed by high doses of chemotherapy or radiation therapy.

🧠 Interesting Facts About Cancer
- Skin cancer is the most common cancer worldwide.
- Early detection significantly increases survival rates. For example, early-stage ovarian cancer has a five-year survival rate of over 90%.
- Lifestyle choices play a significant role in cancer risk; approximately 30-50% of cancers can be prevented by healthy lifestyle choices. (Life Imaging FLA, World Health Organization (WHO))

कैंसर : सामान्य जानकारी
Read In English / हिन्दी में पढ़ें
🧬 कैंसर क्या है? (What is Cancer?)
कैंसर (Cancer) एक ऐसी बीमारी है जिसमें शरीर की कोशिकाएँ (Cells) अनियंत्रित रूप से बढ़ने लगती हैं और अन्य हिस्सों में फैल सकती हैं। यह शरीर के किसी भी भाग से शुरू हो सकता है। सामान्यतः कोशिकाएँ नियंत्रित ढंग से विभाजित होती हैं, लेकिन जब यह नियंत्रण टूटता है, तो कोशिकाएँ एक गाँठ (Tumor) बना सकती हैं। यह गाँठ कैंसरयुक्त (Malignant) या गैर-कैंसरयुक्त (Benign) हो सकती है।
📖 स्रोत: Cancer.org
🧾 कैंसर होने के कारण क्या हैं? (What Causes Cancer?)
कैंसर कोशिकाओं के डीएनए (DNA) में बदलाव यानी म्यूटेशन (Mutation) की वजह से होता है। ये बदलाव अनुवांशिक (Inherited) भी हो सकते हैं या जीवनशैली व वातावरण से भी हो सकते हैं।
मुख्य कारण:
- तंबाकू और धूम्रपान (Tobacco & Smoking)
- अस्वस्थ खानपान व मोटापा (Poor Diet & Obesity)
- अल्कोहल का अत्यधिक सेवन (Excessive Alcohol)
- सूरज की UV किरणें और रेडिएशन (Sun & Radiation Exposure)
- वायरस और बैक्टीरिया (HPV, Hepatitis B, H. pylori)
📖 स्रोत: WHO, Cancer Research UK
🧪 कैंसर की पहचान कैसे होती है? (How Is Cancer Diagnosed?)
कैंसर की पहचान कई तरीकों से की जाती है:
- शारीरिक जांच और इतिहास (Medical History & Physical Exam)
- ब्लड या यूरीन टेस्ट (Lab Tests)
- इमेजिंग टेस्ट (X-ray, CT Scan, MRI, PET Scan)
- बायोप्सी (Biopsy): कोशिका का नमूना निकालकर सूक्ष्मदर्शी से परीक्षण

🧬 कैंसर के प्रकार (Types of Cancer)
कैंसर के 100 से भी अधिक प्रकार हैं। प्रमुख श्रेणियाँ:
- Carcinoma – त्वचा या अंगों की लाइनिंग में शुरू होता है
- Sarcoma – हड्डी, मांसपेशी, वसा आदि में
- Leukemia – खून और अस्थि मज्जा (Bone Marrow) में
- Lymphoma और Myeloma – इम्यून सिस्टम की कोशिकाओं में
- Central Nervous System Cancers – मस्तिष्क और स्पाइनल कॉर्ड

- Radiation Therapy – ऊर्जावान किरणों से कैंसर कोशिकाओं को मारना
- Chemotherapy – दवाओं द्वारा कोशिकाओं को खत्म करना
- Immunotherapy – शरीर की प्रतिरक्षा प्रणाली को मज़बूत करना
- Targeted Therapy – विशेष अणुओं को निशाना बनाना
