Blood in saliva in morning after sleeping

There’s a difference between blood in the saliva and coughing up blood.

There are 3 cancers that can cause blood to be in your saliva. You need not cough to see it.

Blood in the saliva means that if you spit (no coughing, just a voluntary spitting), you may see red.

It also means that you will invariably taste the blood.

There are a number of cancers that cause blood to appear in phlegm that is coughed up, such as lung and esophageal cancer.

Some of this blood, from a mechanical standpoint, may end up retained in your mouth—not all of it will be coughed out.

So technically, you’ll have “blood in the saliva.”

But in the absence of coughing it out, here are the three cancers that may cause blood to be in your saliva:

• Mouth/Oral (includes cheeks and gums)
• Pharynx/Throat (includes tonsils, adenoids and uvula)
• Leukemia

“Blood in the mouth/saliva can be from many different sources and most probably, none of them are from cancers,” points out Daniel Vorobiof, MD, former medical oncology director of The Sandton On
