I have not been sleeping well for the last few days. Yesterday, I slept past 2am but woke up at 4.30am and after that could not fall back asleep. After coming back from Selayang Hospital, I was feeling very tired and also sleepy. This morning, I also felt some pain on my chest area. It felt tight and I also experienced slow breathing. I will take some rest after lunch.
I read something interesting on preventing cancer from spreading and thought I share it with you.
Scientists have discovered that a protein called JAK triggers contractions in tumors which allows cancer cells to squeeze though tiny spaces and spread, in research published in Cancer Cell. Tumors consist of cancer cells, tumor-associated healthy cells and scaffolding that sticks everything together called the cell matrix. Cancer cells spread by moving from the tumor, through this matrix, to new locations.
When cancers spread, a process known as metastasis, they become more difficult to treat, as secondary tumors tend to be more aggressive. It is thought that 90% of cancer-related deaths occur after metastasis.
JAK is not a new culprit in cancer. It has been linked to leukemia, so some drugs are already being developed which target the protein. Dr Lesley Walker, Cancer Research UK's director of cancer information, said: "A huge challenge in successfully treating cancer is stopping it from spreading around the body, and keeping cancer that has already spread at bay."
If the doctors are able to develop a drug to keep the cancer from spreading, then survival rates from cancer treatment will improve drastically.
