Final answer:
A benign self-limiting breast tumor resulting from a new disorganized cell growth is known as a hamartoma, which is composed of an abnormal mixture of cells and tissues but is not malignant.
Step-by-step explanation:
The question asks to identify a benign self-limiting breast tumor that is the result of a new disorganized growth of cells. Among the options provided:
- Sarcoma is a type of malignant tumor that arises from connective tissues.
- A radial scar is a breast lesion that may look like a malignancy on mammograms, but it is not a tumor.
- Invasive lobular carcinoma is a type of breast cancer that has the potential to spread to other parts of the body.
- A hamartoma is a benign (non-cancerous) growth made up of an abnormal mixture of cells and tissues that are normally found in the area of the body where the growth occurs, and it represents a disorganized growth that often self-limits.
Therefore, the correct answer is D. Hamartoma.
