works with white blood cells

esophagus and stomach location

due to this placement of the stomach, it is very clear to see why parts of the stomach is used in a esophagectomy

larger amount of time is used for digestion or choking could occur

causes choking

recurring cancer

helps with easing symptoms and overall pain

A recommended treatment to ensure comfortable life

Low red blood cells and hemoglobin

red blood cells are in charge of oxygen deliver

used in any stage

causing cancer.

Creating a NEW esophagus

Using parts of the stomach, chest and neck

causes cancer

alcohol

a example of esophageal cancer

Combining Tobacco and Alcohol increase risk of Cancer

due to the inability to provide a passageway for air to come in and out

causing many negative effects

Difficultly in breathing

coughing up blood

The thinner lining of the esophagus

Stage 0 cancer

Some esophgaual cancer cells contain a HER2 protein

HER2 protein allows the cancer to grow and spread

Targeted therapy targets these proteins using drugs

a huge warning of cancer and internal bleeding

TREATMENTS?

Palliative care

Targeted Therapy

Chemotherapy

Kills and stops cancer cells from growing

Esophagectomy

removing most of the esophagus and surringing tissues

Common treatment for EARLY stage esophageal cancer

HOW IS IT DIAGNOSED?

Esophagogastroduodenoscopy (EGD)

Doctors take a piece of tissue to use during a biopsy

Using a endoscope to look at your esophagus

Barium swallow

X-Ray used on your esophagus

You must drink a liquid called; Barium

helps doctors with seeing the X-ray better

SYMPTOMS?

Chronic Cough

Only concerning if lasted for more then 4 weeks / few months

coughing blood

Weight Loss

A change in your metabolism and appetite

HeartBurn

HCL acid from the stomach rising to the esophagus

this creates a burning sensation in your esophagus

Smoking can lead to heart burn

WHERE IS IT LOCATED?

WHAT SYSTEMS ARE INPACTED?

BLOOD

Triggers Anemia

Caused by low oxygen deliver

Iron deficiency

Respiratory System

Trachea

the trachea being affected causes the gas exchange to be effected

Allows inspired and expired air to pass in and out

located in front of the esophagus

when affected by SCC, the trachea suffers from internal bleeding

Lungs

function: bring oxygen into our bodies and exhaling CO2

chest pain

fluid around the lungs

this causes the tissue in your lungs to become inflamed resulting in chest pain

coughing blood

Digestive system

Liver

function: produces bile, stores carbohydrates, vitamins and detoxify substances in the blood

the most common place for esophageal cancer to spread

cancer blocks the blood flow in the liver

causing liver damage

creating upper abdominal pain

if the blood flow is blocked, then the liver is unable to detoxify substances

Esophagus

function: transporting food to the stomach

when the cancer prevents proper swallowing, this function becomes slowed down

Prevents swallowing

could go down your windpipe

slows down digestion process

Stomach

Weightloss

causes indigestion which impacts the body greatly

rapid heartburn

Black stools

prominent step in chemical digestion

Contains HCL acid to breakdown bolus

Breakdown of bolus, helps the process of digestion

forms chyme which is removed out of the body

In the lining of the esophagus

Spreads throughout the body

HOW IS IT CAUSED?

Oncogenes

when altered they cause uncontrollable cell growth

genes helping cell growth

Tumor dominant genes

when variants occur in these genes, it loses control over cell growth

genes that work in stopping cell growth when needed

addications

Tobacco

Increases SCC and adenocarcinoma

Alcohol

Increases SCC cancer

WHAT IS IT?

Has two separate types

Adenocarcinoma

Ways adenocarcinoma spreads

lymphatic system

Defends body against infections

Keeps the bodily fluids balanced

Part of the immune system

Blood steam

Surrounding tissues

Begins in the Glandular cells

Affects the lower part of the esophagus

Squamous cells carcinoma (SCC)

SC are located in the lining of the esophagus

Creates Squamous cells (SC)

Found in the middle and upper part of the esophagus
