Cancer Disparities Examples

Cancer health disparities are differences among populations in their treatment and diagnosis of cancer. This is due to social, environmental, and economic disadvantages. 


State University of New York at Stony Brook

- Cancer is a term that refers to a collection of diseases in which some of the body's cells divide uncontrollably and invade surrounding tissues. 
- Cancer can metastasize, i.e., spread to other parts of the body. Metastatic cancer is hard to treat and tends to be fatal. Most cancer deaths are caused by metastasis.

This node should be a relation node, but I can't delete it since it's a root node of the "cancer" tree and it has two upvotes.

- Many cancer treatments work by suppressing rapidly-dividing cells. Note that cancer cells divide rapidly, but some healthy cells (e.g., white blood cells) also divide rapidly. Hence, the immune system weakens, making the patient more likely to get infected and experience severe COVID-19 complications.

COVID-19 and Cancer Comorbidity

- Note: Having some cancer symptoms/signs doesn't mean one has cancer. Also, many cancers don't have clear signs/symptoms, especially during the early and middle stages.

General Signs/Symptoms of Cancer
- Unexplained weight loss
- Fever
- Fatigue
- Pain
- Skin changes

Signs/Symptoms of Specific Cancers
- Changes in bowel/bladder functions
- Sores that don't heal
- White patches in mouth or on the tongue
- Unusual bleeding/discharge
- Thickening or lump in part(s) of the body
- Persistent Indigestion or swallowing difficulties
- Persistent, "nagging cough or hoarseness"
- Other major changes in how one feels or one's body functions

Signs and Symptoms of Cancer

- Treatment resistance
- Types of treatment (e.g., surgery, chemotherapy, radiotherapy)
- Treatment approaches/aspects (e.g., palliative care, precision medicine)
- Other treatments (e.g., hyperthermia, complementary medicine)

Cancer | References Used

According to the American Cancer Society (original source) and https://cancer80.weebly.com/ (secondary source), 
- In the USA, 1 in every 3 people will get cancer at some point in their lives, and cancer causes 1 in every 5 deaths. 
- Most of us will have a parent, sibling, relative, or friend who eventually dies from cancer.
- Cancer takes a financial, emotional, and psychological toll on patients and caregivers.

Impact of Cancer

According to the American Association for Cancer Research (AACR),
- 4 in every 10 cancer cases are preventable.
- Tobacco smoking (19%), excess body weight (8%), alcohol (6%), UV radiation (5%), poor diet (5%), infections (4%), and sedentary lifestyles (3%) are the main preventable risk factors for cancer.
- Numbers in parentheses indicate % of US cases in adults age >30 attributable to the indicated risk factors.

Preventable Causes of Cancer

Financial toxicity is when patients struggle with the severe financial burden of cancer treatments. It causes severe distress -- sometimes more than the cancer itself -- even pushing many patients to skip treatment.

Cancer Disparities 

Mutant HTT (huntingtin) directly interacts with p53, a tumor suppressor whose mutation is responsible for breast cancers, in mice and flies. Although not always, the phosphorylation of HTT can also induce neuro protectiveness in individuals with Huntington’s and can help regulate cell differentiation and localization. Overall, there is 80% less rate of cancer amongst people with Huntington's than the normal population.

Connection Between Cancer and Huntington's

Cancer forms in the cells of the breasts. Breast cancer can occur in women and rarely in men. Symptoms of breast cancer include a lump in the breast, bloody discharge from the nipple, and changes in the shape or texture of the nipple or breast.
