Understanding Cancer
Cancer is a broad term for diseases characterized by abnormal cell growth that can invade surrounding tissues and spread to other parts of the body (metastasis). There are more than 100 types of cancer, including breast, lung, prostate, colorectal, and blood cancers.
Cancer begins when genetic mutations disrupt normal cell behavior. Tumors can be benign (non-cancerous) or malignant (cancerous). Malignant tumors invade nearby tissues and can spread, making early detection and treatment life-saving.
Fact: According to global health data, nearly 1 in 6 deaths worldwide is due to cancer, yet early detection improves survival rates significantly.
Symptoms to Watch For
Cancer symptoms vary based on the type and location, but common warning signs include:
- Unexplained weight loss
- Persistent fatigue
- Changes in skin or new moles
- Unusual lumps or swelling
- Persistent pain
- Changes in bowel or bladder habits
- Persistent cough or hoarseness
- Bleeding or bruises without cause
Case Study:
Mr. Kumar, 55, noticed persistent coughing and unexplained weight loss. After consulting doctors and running tests, he was diagnosed with early-stage lung cancer. Early treatment helped him avoid advanced spread and achieve remission.
These early signs shouldn’t be ignored. If you notice anything unusual, explore support and shared experiences on the MyHospitalNow cancer forum.
Causes of Cancer
Cancer results from a complex interplay of genetic, environmental, and lifestyle factors. Some common causes include:
1. Genetic Factors
Certain cancers run in families, and genetic mutations like BRCA1 and BRCA2 increase breast and ovarian cancer risk.
2. Lifestyle Habits
- Smoking and tobacco use
- Alcohol consumption
- Poor diet and obesity
- Sedentary lifestyle
3. Environmental Exposures
- Radiation (UV rays)
- Industrial chemicals
- Air pollution
4. Infections
- HPV (linked to cervical cancer)
- Hepatitis B and C (linked to liver cancer)
- Helicobacter pylori (linked to stomach cancer)
5. Age
Cancer risk increases with age as genetic damage accumulates.
Understanding the causes helps patients adopt preventive measures like lifestyle changes and regular screenings.
Treatment Options for Cancer
Treatment depends on cancer type, stage, and patient health. Here are common approaches:
1. Medical Management & Supportive Care
- Chemotherapy
- Hormone therapy
- Targeted therapy
- Immunotherapy
- Supportive care (pain management, nutrition, counseling)
2. Radiation Therapy
High-energy rays used to kill cancer cells or shrink tumors.
3. Surgical Interventions
Surgery may be used to remove tumors or affected tissue. Common surgical procedures include:
- Tumor resection (removing cancerous growth)
- Mastectomy (breast removal for breast cancer)
- Prostatectomy (prostate removal)
- Colectomy (removal of part of the colon)
- Debulking surgery (reducing tumor size before other treatments)
4. Multimodal Treatment
Often, cancer care involves a combination of surgery, chemotherapy, and radiation.
Tip: Your treatment plan should be designed by a multidisciplinary cancer care team for the best outcomes.
