Cancer symptoms can be ill-defined, so in many cases they are ignored. Current pressures on cancer care, however, highlight the urgent need to educate the public about the warning signs. According to health organizations, many people with lung cancer report seeing changes in the appearance of their face.

An entry posted on the Reynolds Cancer Support House health website outlines the symptoms of cancer that women are “most likely to overlook.”

The health body continues: “Some lung cancer patients report noticing puffiness, swelling or redness in the face.

“The explanation for this is that small cell lung tumors usually block blood vessels in the chest, preventing blood from flowing freely from the head and face.”

These changes are considered a “common sign” of lung cancer, but they can also occur with several other types of cancer.

Carcinoid tumors, for example, are neuroendocrine tumors that grow specifically in neuroendocrine cells.

These are responsible for transmitting signals through the release of hormones to help the body function.

When the cells become infested with cancer, symptoms include hot, red facial flushing, diarrhea and wheezing.

Research suggests that facial flushing is the result of cardioid syndrome, which is induced by too many hormone-like substances released into the blood.

DO NOT MISS :

Squamous cell carcinoma, which is a skin cancer, is also known to alter the appearance of the face.

These changes often occur in the parts of the face most likely to be exposed to the sun.

When lung cancer causes facial swelling, it’s usually because the tumor is pressing on the vein leading from the head to the heart.

This obstruction slows the flow of the block to and from the head, causing swelling around the neck and face.

Research on the psychological impact of these changes has shown that they have a considerable effect.

It is important not to let any drastic body changes go untreated by an expert, as screening tests can help detect malignant tumors at an early stage.

How to Prevent Cancer

Fortunately, several preventive measures can be taken to reduce the risk of cancer.

Exposure to radiation, industrial and environmental toxins, infections and smoking should be avoided.

Exercise and proper diet are two equally important measures in preventing cancer, as both help keep the body lean.

Although the research linking cancer to sleep isn’t strong, sleep quality should be a priority.

Indeed, “insufficient and inadequate sleep is associated with weight gain, which is a risk factor for cancer,” says Harvard Health.

Finally, an adequate intake of vitamin D may offer some protection against several cancers, including prostate and colon cancer.
