Patients generally exhibit a unique combination of these and other neurological symptoms. The most important thing is to get a rapid diagnosis. PCD is most common in patients with lung, breast, ovarian, or lymphatic cancers. Some patients are diagnosed with PCD before locating their primary cancer. The syndrome can also appear well after tumor excision, chemotherapy, and radiation have already taken place.
Some patients have great difficulty identifying the location of their cancer.
PCD effects almost as many women as men, but is very slightly more common in males. There have been some reported cases where the symptoms have abated upon tumor excision, chemotherapy, radiation, etc. It is therefore important to locate the source of the cancer and work to eradicate it, if at all possible. It is therefore important to get a proper diagnosis through antibody testing. This blood cleansing technique can ease the symptoms of PCD, and can sometimes arrest any progression of neurological dysfunction so it is important that patients avail themselves of this treatment as soon as possible.
