Final answer:
The most commonly diagnosed type of cancer that results in very few deaths is basal cell carcinoma, a type of skin cancer. It represents about 40% of all new cancer cases in the US and is highly treatable.
Step-by-step explanation:
Overview of the Most Common Nonlethal Cancer,
The type of cancer that is most commonly diagnosed but results in very few deaths is basal cell carcinoma. This type of skin cancer accounts for about 40% of all new cancers each year in the United States and is usually very treatable. Basal cell carcinoma is generally caused by excessive exposure to ultraviolet light, such as from the sun or tanning beds. Unlike more fatal cancers like lung, colorectal, prostate, and breast cancer, basal cell carcinoma typically does not spread to other parts of the body and can often be removed without serious complications.
It is important to note that while basal cell carcinoma has a high survival rate, other types of cancer like lung cancer are associated with a much higher mortality rate. Lifestyle factors, including tobacco use, play a significant role in the likelihood of developing certain cancers.
Screening and early detection methods, such as those used for cervical cancer in high-income countries, have contributed to reducing death rates from some types of cancer. However, in low-income countries, lack of access to such screening procedures can lead to higher mortality rates from cancers that might otherwise be treatable.
