5. Coughing Up Phlegm Speckled With Blood
One of the most important parts of your respiratory diaphragm is the superior vena cava, the superior of the two veins that help to carry blood from your cranium to the heart. If you have lung cancer these veins may find themselves squashed by growths and tumors pressing against them. As such you may notice your neck and face beginning to swell up.
Around the same time, you may find specks of blood mixed with phlegm coming out every time you cough. This can become quite deep and extremely intense. Your airways may also get inflamed as the tumor continues to pressure these veins. Another thing to look out for is when your breaths start to come out with wheezing sounds, and although this can be linked to conditions such as asthma, it is within your best interest to seek out the consultation of a doctor. Granted a combination of these occur.
