Final answer:
The most widespread types of cancer are skin cancer (especially basal cell carcinoma), lung cancer, prostate cancer in males, and breast cancer in females. Lung cancer, primarily caused by smoking, is the deadliest type, mainly due to its late detection. Other common cancers include colorectal and stomach cancers, with various causes ranging from behavior to environmental factors.
Step-by-step explanation:
Common Types and Causes of Cancer
The most prevalent types of cancer include skin cancer, specifically basal cell carcinoma, which accounts for about 40% of all cancers diagnosed in the United States annually. Another common form is breast cancer, particularly among females, with increased risk as they age. Among the deadliest cancers is lung cancer, primarily caused by tobacco smoke exposure. While not the most common in incidence, lung cancer causes the most deaths due to cancer because it is often detected at a late stage and is associated with aggressive progression.
In men, prostate cancer is highly common, while women more frequently face breast cancer. Other cancers with high prevalence are colorectal and stomach cancers. Pediatric cancers notably differ, with types like acute lymphoblastic leukemia and brain tumors being more common among children.
Cancers may have a variety of causes from genetic predispositions to behavioral risk factors such as smoking, overexposure to ultraviolet light, alcohol consumption, poor diet, and inadequate weight control. These causes, combined with environmental factors, contribute to the onset and development of different types of cancer.
