Hi, I'm wk lee and l fully understand what you are going through. My wife is a 4th stage cancer patient in remission and we have learnt a lot through our experience and contacts. I am a committee member of a cancer NGO called Cansurvive Centre Malaysia Bhd where we organise monthly free talks pertaining to health and cancer. Please PM me with your contact number if you would like to be added to our Support Group Chat.
It may also be of interest to note that , through my contacts and research, I have come across an immunotherapy in Malaysia with a 90% chance of permanent remission ( subject to review and case acceptance by doctor) ! There is hope for cancer survivors, regardless of stage.
