PATHOLOGY

Detailed explanation-1: -There, white blood cells called lymphocytes can attack and kill the bacteria. Viruses and cancer cells are also trapped and destroyed in the lymph nodes. More lymphocytes are produced when you have an infection. That is why your lymph nodes tend to swell when you have an infection.

Detailed explanation-2: -Your lymph nodes get larger when more blood cells come to fight off an invading infection. They all essentially pile in, causing pressure and swelling. Often, the lymph nodes that swell will be close to the infection’s site.

Detailed explanation-3: -Lymph nodes produce immune cells to help fight infection. They also filter the lymph fluid and remove foreign material, such as bacteria and cancer cells. They can become swollen from inflammatory conditions, an abscess, cancer, and most commonly from infection.

Detailed explanation-4: -Having swollen lymph nodes usually means that your immune system is fighting an infection in the area. For example, if you have a sore throat from a virus, you may get swollen neck glands. An infection on your leg can cause swollen glands in the groin.

Detailed explanation-5: -Enlargement of the lymph nodes is a normal step in combating infection, but it also occurs during autoimmune responses. One possibility for combating lymph node growth during autoimmunity is antiangiogenic drugs, which were developed to combat tumors.
