Final answer:
Increased lymphoid tissue can increase the risk for lymphoma due to the abnormal growth of lymphatic cells.
Step-by-step explanation:
Increased lymphoid tissue can lead to an increased risk for lymphoma. Lymphoid tissue, such as lymph nodes, spleen, and Peyer's patches, play a crucial role in the immune system by producing and storing lymphocytes, which are specialized white blood cells involved in immune responses. However, when there is an abnormal growth of lymphoid tissue, it can increase the chances of mutations and the development of cancerous cells, including lymphoma.
