TED Talk: William Li: Can We Eat to Starve Cancer?

Define angiogenesis:

• Angiogenesis is the process by which new blood vessels form from pre-existing vessels.

• Angiogenesis is the process by which nerve cells regenerate after injury.

• Angiogenesis is the process by which white blood cells attack pathogens.

• Angiogenesis is the process by which bone tissue is replaced during growth.

Define capillaries:

• Capillaries are the smallest blood vessels in the body, connecting arterioles and venules and facilitating the exchange of oxygen, nutrients, and waste between blood and tissues.

• Capillaries are large blood vessels that carry blood directly from the heart to the lungs.

• Capillaries are the thickest blood vessels responsible for pumping blood throughout the body.

• Capillaries are blood vessels that only transport waste products away from tissues.

Approximately how many capillaries are found in the human body?

• About 10 billion

• About 1 million

• About 100 million

• About 1 trillion

Blood vessels grow in the adult human body under which circumstances?

• During wound healing and tissue repair

• During sleep

• During digestion of food

• During physical exercise only

List a few diseases that occur during insufficient angiogenesis:

• Ischemic heart disease, stroke, delayed wound healing

• Cancer, psoriasis, arthritis

• Diabetic retinopathy, tumor growth, obesity

• Asthma, eczema, migraine

List a few diseases that occur during excessive angiogenesis:

• Cancer, diabetic retinopathy, rheumatoid arthritis

• Asthma, tuberculosis, influenza

• Hypertension, diabetes, obesity

• Alzheimer's disease, Parkinson's disease, epilepsy

Microscopic cancers are very prevalent; however they don’t always grow. Why not?

• Because the body’s immune system can suppress or eliminate them.

• Because they always lack nutrients to grow.

• Because they are always benign.

• Because they never receive blood supply.

The purpose of antiangiogenic therapy is:

• to inhibit the formation of new blood vessels

• to stimulate immune response

• to promote cell division

• to increase oxygen delivery to tissues

What was given to Milo, the boxer, to treat his malignant tumor?

• Chemotherapy

• Antibiotics

• Painkillers

Since 2004, what has been the percentage of survival rate increase for metastatic kidney cancer when treated with antiangiogenic therapy?

• 10%

• 20%

• 30%

• 40%
