Questions: Biology 106: Pathophysiology E: Kidney failure Laura, at the age of 32 , is diagnosed with kidney cancer. From a statistical point-of-view, what type of cancer does Laura probably have? Renal adenocarcinoma Wilms' tumor Renal cell carcinoma Renal pelvis carcinoma I don't know

The answer is the third one: Renal cell carcinoma.

Explanation for each option:

1. Renal adenocarcinoma: This term is not commonly used in the context of kidney cancer. Adenocarcinoma typically refers to cancers that form in mucus-secreting glands, and while it can occur in the kidneys, it is not the most common type.
2. Wilms' tumor: This is a type of kidney cancer that primarily affects children, not adults. Laura, being 32 years old, is unlikely to have Wilms' tumor.
3. Renal cell carcinoma: This is the most common type of kidney cancer in adults. It originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidney that transport primary urine.
4. Renal pelvis carcinoma: This type of cancer occurs in the renal pelvis, the area of the kidney where urine collects before moving to the bladder. While it is a type of kidney cancer, it is less common than renal cell carcinoma.
5. I don't know: This option is not applicable as we are providing an informed answer.

Summary: Laura, at the age of 32, is most likely to have renal cell carcinoma, which is the most common type of kidney cancer in adults.
