Yeah. Actually- actually most most cancers. I mean, especially in the abdomen, they can come pretty vague. It does come as simple discomfort or, you know, once you- once you start getting things like weight loss, loss of appetite, usually quite significant already. So, yeah because of this vague symptom some, some, I guess, not just some most Malaysians have- I mean nobody really likes to see the doctor. Whatever's said and done. So people treat it as maybe just a simple gastric pain. You know just go buy some medication and self-treat. Or sometimes they see doctors and it's not picked up. They don't have a suspicion that it may be something else. So after left alone to fester for a while it might grow, and by the time it's actually caught, when it's giving these other symptoms like loss of weight, or maybe more severe pain, or if they turn a little bit yellow or what we call jaundice. Those - at that point it may be a bit too late, it may be a bit too advance. Yeah. So that's why it's a little bit harder to treat them.
