Cancer Types
Explore detailed information about major cancer types, including statistics, risk factors, screening methods, and prevention strategies.
Breast Cancer
Breast cancer begins in the cells of the breast. It can occur in both men and women but is far more common in women. Regular screening and awareness of changes can lead to early detection.
Key Facts
- 1 in 8 women will develop breast cancer in their lifetime
- Early detection through mammography saves lives
- Treatment options have improved significantly
Early Warning Signs
- New lump or mass
- Swelling of all or part of a breast
- Skin irritation or dimpling
- Breast or nipple pain
Key Statistics
99% 5-year relative survival rate when detected early
American Cancer Society
Risk Factors
- Age (risk increases with age)
- Family history of breast or ovarian cancer
- Genetic mutations (BRCA1, BRCA2)
- Hormone replacement therapy
Screening Methods
- Clinical breast exam
- Mammography
- Breast MRI
- Genetic testing for high-risk individuals
Prevention Tips
- Limit alcohol consumption
- Maintain a healthy weight
- Stay physically active
- Know your family history
Lung Cancer
Lung cancer is the leading cause of cancer death globally. While strongly linked to smoking, non-smokers can also develop lung cancer. Low-dose CT screening is recommended for high-risk individuals.
Key Facts
- Responsible for more deaths than any other cancer
- Smoking causes about 80% of lung cancer deaths
- Low-dose CT scans can detect early-stage lung cancer
Early Warning Signs
- Persistent cough
- Coughing up blood
- Chest pain
- Unexplained weight loss
Key Statistics
63% higher survival rate when detected at an early stage
Lung Cancer Research Foundation
Risk Factors
- Tobacco smoking
- Radon gas exposure
- Asbestos exposure
- Air pollution
Screening Methods
- Low-dose CT scan
- Chest X-ray
- Sputum cytology
- Biopsy
Prevention Tips
- Don't smoke or quit smoking
- Avoid secondhand smoke
- Test your home for radon
- Avoid asbestos exposure
Colorectal Cancer
Colorectal cancer starts in the colon or rectum. It often begins as a growth called a polyp, which can be found and removed before it turns into cancer. Regular screening is key to prevention.
Key Facts
- Third most common cancer diagnosed in the US
- Polyps can be removed before becoming cancerous
- Screening can prevent colorectal cancer
Early Warning Signs
- Change in bowel habits
- Blood in stool
- Abdominal discomfort
- Unexplained weight loss
Key Statistics
90% 5-year survival rate when detected at the localized stage
Colorectal Cancer Alliance
Risk Factors
- Age over 50
- Personal or family history of polyps
- Inflammatory bowel disease
- Low-fiber, high-fat diet
Screening Methods
- Colonoscopy
- Stool-based tests (FIT, Cologuard)
- CT colonography
- Sigmoidoscopy
Prevention Tips
- Get regular screening after age 45
- Eat a diet rich in fruits and vegetables
- Exercise regularly
- Limit red and processed meat
Prostate Cancer
Prostate cancer develops in the prostate gland, a small walnut-shaped gland in men. Some types grow slowly and need minimal treatment, while others are aggressive and spread quickly.
Key Facts
- 1 in 8 men will be diagnosed in their lifetime
- Most prostate cancers are adenocarcinomas
- African American men face higher risk
Early Warning Signs
- Difficulty urinating
- Frequent urination, especially at night
- Blood in urine or semen
- Erectile dysfunction
Key Statistics
Nearly 100% 5-year survival rate for localized prostate cancer
Prostate Cancer Foundation
Risk Factors
- Age over 50
- Family history
- Race (more common in African American men)
- Obesity
Screening Methods
- PSA (Prostate-Specific Antigen) blood test
- Digital rectal exam (DRE)
- MRI
- Biopsy
Prevention Tips
- Maintain a healthy diet
- Exercise regularly
- Discuss screening with your doctor
- Know your family history
Skin Cancer
Skin cancer is the most common cancer worldwide. Melanoma, while less common, is the most dangerous. Protection from UV radiation and regular skin checks are essential.
Key Facts
- More than 5 million cases diagnosed annually in the US
- Melanoma accounts for the most skin cancer deaths
- Early detection dramatically improves outcomes
Early Warning Signs
- New or changing moles
- Asymmetrical growths
- Irregular borders or colors
- Itching or bleeding spots
Key Statistics
99% 5-year survival rate for melanoma when caught in Stage I
Skin Cancer Foundation
Risk Factors
- Excessive UV exposure
- Fair skin, light hair, freckles
- History of sunburns
- Weakened immune system
Screening Methods
- Visual skin exam by a dermatologist
- Dermoscopy
- Skin biopsy
- Self-examination of moles and spots
Prevention Tips
- Apply broad-spectrum sunscreen daily
- Avoid peak sun hours (10am–4pm)
- Wear protective clothing
- Don't use tanning beds
Cervical Cancer
Cervical cancer is caused by persistent infection with certain strains of the human papillomavirus (HPV). Vaccination and regular Pap/HPV screening have dramatically reduced cervical cancer rates.
Key Facts
- Almost all cases are caused by HPV
- The HPV vaccine can prevent most cases
- Regular screening is highly effective
Early Warning Signs
- Abnormal vaginal bleeding
- Pelvic pain
- Unusual vaginal discharge
- Pain during intercourse
Key Statistics
Nearly 100% survival rate when caught in early stages
World Health Organization
Risk Factors
- HPV infection
- Smoking
- Long-term use of oral contraceptives
- Weakened immune system
Screening Methods
- Pap smear
- HPV test
- Colposcopy
- Biopsy
Prevention Tips
- Get the HPV vaccine
- Have regular Pap/HPV screening
- Don't smoke
- Practice safe sex
Thyroid Cancer
Thyroid cancer affects the thyroid gland in the neck. Most thyroid cancers are highly treatable, especially when found early. Incidental detection on imaging has increased diagnosis rates.
Key Facts
- Most common in women aged 25–65
- Incidence rates have been increasing
- Excellent prognosis with early treatment
Early Warning Signs
- Lump or nodule in the neck

- Thyroid scan
Prevention Tips
- Know the symptoms of thyroid changes
- Discuss risk factors with your doctor
- If exposed to radiation, get regular checkups
- Be aware of family history
Pancreatic Cancer
Pancreatic cancer is one of the deadliest forms of cancer, largely because it's often diagnosed late. Research is advancing rapidly, and early detection can improve outcomes significantly.
