Onco says Herceptin does not cause side effects even though the manufacturers of herceptin says it can. So, the peripheral neuropathy, sore throat, itchy rash, ridged and cracked nails, breathlessness...
You know...they believe 6 months of herceptin is enough now...but until clinical trials are finished I guess they will continue. So ...if it really is becoming unbearable you could vobsider stopping 2 short in consultation with your oncologist to be sure.
