No, it could also occur in the lymph nodes on the sides of your neck.
what kind of infection can cause a swollen lymph node in the left breast
When to See a DoctorIt could be a simple infection of your lymph glands or something more serious like breast cancer. It would be wise to see your doctor.

The truth is that it could start anywhere on your breast. But most of the times breast cancers start on your left breast and on outer and upper quadrant (if you divide breast in four parts by two perpendicular lines).
You may have an infection in your lymph nodes. You should seek the advice from your physician and get some rest.Ê
There are several different things that can cause swelling of the lymph nodes on the sides of your neck. Some of these things include an injury, an infection, or there could be a tumor on the lymph node.
You have an infection and your lymph nodes are acting up because of it.
When someone has an infection in the general area of a lymph node (such as in the scalp.. the nodes being in the neck) or when you have a viral infection (like "mono") the lymph nodes don't just swell... the actually grow in size to better filter/fight the infection/virus. Once the infection/virus is gone, the nodes shrink down somewhat, but never shrink to the size they were prior to the infection/virus. You're left with a firm knot... I've got several small firm nodes from when I was a child (60+ years ago)...
IMMEDIATELY !
I have heard a tooth infection can infect your brain if left untreated. But it is supposed to be very rare.
Enlarged lymph nodes are a response to the infection. You need to get the infection treated, probably with antibiotics. If the infection keeps returning you may need to have your tonsils out. Even if there are no other symptoms, repeated tonsilitis can result in problems. Most often, tonsilitis is caused by a strep infection which can turn bad resulting in complications. Make sure that you follow your doctors instructions.
