The said injuries can occur if the individual experiences trauma or if the person is into sports or other athletic activities. Due to this, the person may experience problems in having the arm moved upward, swelling, and pain. Teens and children are more prone to this kind of injury as the collarbones mature once individuals reach the age of 20. Older adults may also be at risk for such injuries due to weaker bone density. 

2. Swollen lymph nodes

The body contains 600 lymph nodes in it and can help the body in filtering foreign substances and unwanted bacteria the body as well as helping in the ensuring that white blood cells (WBCs) are properly circulated. These white blood cells can also aid in fighting off illnesses and infections. 

Lymph nodes can start swelling if the body becomes injured or if the individual is fighting off an illness or some other infection. This is due to the body transporting more white blood cells to the lymph nodes to help fight off the problem. This condition can lead to the development of a lump or swelling near or on the collarbone. It is best to seek medical assistance if this swelling does not go away after several weeks so that the doctor can rule out other possible conditions that may be severe or serious.

3. Cyst

The collarbone lump that one has can also be a tumor. These can either be malignant (cancerous) or benign (noncancerous). For malignant tumors, the doctor needs to have the tumor monitored and further evaluated. A majority of tumors that are benign are classified as lipomas. These are tumors that are fat-filled and will show up over an extended period commonly after months or years. They can feel squishy and soft if they are touched, but they will mostly be pea-sized or small. The largest tumors are sized almost as big as a quarter (even smaller). Another form of tumor is called a bone tumor with the said cancer rarely developing in the clavicle. A rare kind of tumor that can develop or show up in the collarbone is called the aneurysmal bone cyst. These kinds of tumors will commonly happen to teens and children and can either be cancerous or benign.
