To diagnose and treat a disease, a doctor must evaluate the patient's body at multiple levels of organization. Identify the level of organization relevant to each stage of the process described below. (1) As part of Fred's annual physical, the doctor examined his skin, fingernails and hair for signs of disease. Noticing an unusual lesion on his neck, the doctor referred Fred to a dermatologist. (2) Upon observing the lesion, the dermatologist said, "Yes, this looks like it could be a squamous cell carcinoma, a tumor in the epidermis of the skin." (3) The dermatologist carefully examined all of Fred's skin for signs of additional tumors, but did not find any. (4) The dermatologist removed the lesion and sent it for a biopsy. Under the microscope, the pathologist saw some cells with abnormal morphology and confirmed a diagnosis of squamous cell carcinoma. However, he noted that the margins of the lesion were clear of abnormal cells, and the tumor had been successfully removed.
