In many cases, the treatment of abdominal cancer requires the removal of lymph nodes. This surgical intervention often causes damage to the lymphatic system which compromises its effectiveness in draining fluids.
Fluids and other substances are no longer drained or are drained insufficiently.
Radiotherapy also affects the lymphatic system and its effectiveness. The imbalance between lymphatic load and lymph transport capacity following abdominal cancer surgery may result in a so-called secondary (=acquired) leg lymphedema.
There are rare cases where lymphedema involves the lower abdominal region or the genitals as well. The most common cause of secondary lymphedema is cancer surgery including removal and/or radiation of lymph nodes. The likelihood of edema formation diminishes as the post-operative period increases
To reduce the chances of developing lymphedema, patients need to follow very specific rules.
If, however, a lymphedema does develop, it will require lifelong therapy.
The treatment schedule will depend on the course of the disease. If left untreated, lymphedema will progress in most cases and can assume monstrous proportions (elephantiasis).
