Normal cells<span> listen to signals from neighboring </span>cells<span> and stop growing when they encroach on nearby tissues (something called contact inhibition.) </span>Cancer cells<span> ignore these </span>cells<span> and invade nearby tissues. Benign (non-</span>cancerous<span>) tumors have a fibrous capsule.</span>
Endoplasm<span> generally refers to the inner (often granulated), dense part of a cell's cytoplasm. This is opposed to the </span>ectoplasm<span> which is the outer (non-granulated) layer of the cytoplasm, which is typically watery and immediately adjacent to the plasma membrane.</span>
