The reason why appendix cancer is on the rise is a result of rising obesity rates, poor diet including consuming ultra processed foods, changes in the gut microbiome and alterations of the immune system.
Even though appendix cancer is rare, cases of appendix cancer have also surged 300% to 400% in Millennials and Gen X, when compared to the previous generations.
Modern imaging and better pathology classification also now allows doctors to find tumors that were previously undetected or misdiagnosed.
Soaring rates of obesity since the 1970s are also heavily suspected as an underlying driver of appendix cancer.
And links have also emerged between appendix cancers and alterations in gut bacteria (microbial dysbiosis) as well as the presence of autoimmune diseases.
And high consumption of added sugars, ultra processed foods and preservatives, can cause lingering inflammation and chemical exposure in your intestine also lead to increasing rates of appendix cancer.
Appendix cancer is still considered rare and affects roughly 1 to 2 people per 100,000 people each year.
Only around 1,500 to 3,000 new cases of appendix cancer are diagnosed a year in the United States and most cases of appendix cancer are found by accident during routine surgery for suspected appendicitis or during imaging scans that are done for other reasons.
The common types of appendix cancer include neuroendocrine (carcinoid) tumors, which are the most frequent type of appendix cancer and epithelial adenocarcinomas, which are less common.
There's also an increasing rate of appendix cancer and diagnoses among younger adults including in Gen X as well as Millennials.
The cause of appendix cancer is not known exactly, although what can cause appendix cancer is DNA changes inside of healthy cells in your appendix, and these changes make the cells grow fast and out of control to form a tumor.
Harmful changes inside the cell code tell the cells to keep living when they should die and can lead to appendix cancer.
And most cases of appendix cancer also happen by random chance with no clear trigger or lifestyle cause.
Other linked risk factors for appendix cancer include a family history, age and even a link to certain immune system or gut health conditions.
A small number of cases of appendix cancer are linked to inherited gene changes that are passed down in families and appendix cancer is also found more often in older adults, although appendix cancer can still happen at any age.
The stages of appendix cancer are stages 0 through IV.
Appendix cancer is staged using the American Joint Committee on Cancer or (AJCC) TNM system that assesses the size of tumor, lymph node involvement and the distant metastasis.
For appendiceal adenocarcinoma the stages of the appendix cancer include:
Stage 0 (Carcinoma in situ) appendix cancer is when abnormal cells are found only in the innermost lining of your appendix and have not yet invaded any deeper tissues.
Stage I appendix cancer is when the tumor has grown deeper into the walls of your appendix but has not yet spread to your nearby lymph nodes or other parts of your body.
Stage II appendix cancer is when the cancer has grown through your outer lining of your appendix and may even involve surrounding fatty tissues or nearby organs like your colon, but has not yet reached your lymph nodes.
Stage III appendix cancer is when the cancer has spread to your regional lymph nodes near your appendix, but has not metastasized yet to any distant organs.
And stage IV appendix cancer is the most advanced stage of appendix cancer, in which the appendix cancer has spread to distant parts of your body like your liver or lungs or has spread widely throughout the lining of your abdomen (peritoneum).
And for appendiceal neuroendocrine tumor the stages of the cancer include:
Stage I, the tumor is 2 cm or smaller and has not spread yet to lymph nodes.
Stage II, the tumor is larger than 2 cm and might be growing into surrounding tissue, but has not yet spread to lymph nodes or distant organs.
Stage III, the tumor has spread to nearby lymph nodes or grown directly into neighboring organs and structures.
Stage IV, the cancer has metastasized to distant areas, like the lungs or the liver.
The different types of appendix cancer are neuroendocrine (carcinoid) tumors), Adenocarcinomas (carcinomas) and Mucinous Neoplasms.
Mucinous Neoplasms are a group of epithelial tumors, which can be benign (noncancerous) or have potential to be precancerous, like low grade appendiceal mucinous neoplasms or (LAMN).
And while they are not always malignant, they can still result in PMP if they do rupture and spill their mucinous contents into your abdominal cavity.
Adenocarcinomas (Carcinomas), are tumors that form in your glandular tissue lining inside of your appendix and they are also divided into specific subtypes which include, Mucinous Adenocarcinoma, Colonic type (intestinal type) Adenocarcinoma, Goblet cell Adenocarcinoma (also called adenocarcinoids), and Signet ring Cell Adenocarcinoma.
Mucinous Adenocarcinoma is the second most common type of appendix cancer and these tumors produce a thick, jelly like fluid that is called mucin.
And if the tumor ruptures, the mucin and the cancer cells can also spread throughout your abdomen, which leads to a complex condition called pseudomyxoma peritonei or PMP.
Colonic type (Intestinal Type) Adenocarcinoma develops near the base of your appendix and also behave much like typical colon cancer does.
Goblet cell Adenocarcinoma (also known as adenocarcinoids) are rare and more aggressive tumors that share characteristics of both adenocarcinomas as well as neuroendocrine tumors.
And Signet-ring cell Adenocarcinoma is a very rare and highly aggressive form of appendix cancer in which the cancer cells secrete large amounts of mucin and also have a distinct "signet ring" appearance to them.
Appendiceal cancer is also known as appendix cancer, which are the exact same diseases.
Appendiceal in appendiceal cancer is the medical term and scientific adjective form of the word "appendix".
Appendiceal cancer and appendix cancer are terms that describe a rare condition, in which abnormal cells in your appendix grow out of control to form a tumor.
The symptoms of appendix cancer include abdominal bloating, lower right belly pain, and changes in your bowel habits.
Although appendix cancer usually causes now early signs or symptoms when it begins.
And many cases of appendix cancer are actually found by accident during routine surgery for regular appendicitis.
While appendix cancer often shows no early signs, the common signs and symptoms of appendix cancer include belly pain, bloating and swelling, digestive changes, bowel issues and acute appendicitis.
Belly pain with appendix cancer involves a sharp or vague discomfort in the lower right side of your abdomen or pelvic area.
Bloating and swelling with appendix cancer involves a growing waistline, increased belly size, or even a feeling of fullness that is caused by fluid or even buildup of mucus.
Digestive changes with appendix cancer include vomiting, nausea, loss of appetite or even feeling full very quickly when you start eating.
Bowel issues with appendix cancer include diarrhea, constipation or even just general changes in your bowel habits.
And acute appendicitis with appendix cancer includes sudden inflammation and severe pain which mimics a normal infected appendix.
The advanced symptoms of appendix cancer include intestinal blockage, jelly belly or PMP and other signs like new hernias, unexplained fatigue, shortness of breath or even facial flushing if the appendix cancer spreads.
Jelly Belly (PMP is a condition called pseudomyxoma peritonei where jelly like mucus fills your abdomen and places pressure on your organs.
And intestinal blockage with appendix cancer involves having trouble passing gas or having a full bowel obstruction.
Appendix cancer is a rare form of cancer disease where cells in the appendix grow out of control, frequently identified unexpectedly during surgery for appendicitis or via imaging scans.
Many people have no early symptoms of appendix cancer although they may alter have appendicitis like pain in the lower right abdomen or pelvic region.
The main types of appendix cancer include:
Neuroendocrine (Carcinoid) tumors: The most common type; they grow slowly in the hormone-producing cells of the organ.
Adenocarcinomas: Epithelial tumors starting in the lining cells, which can be mucinous (producing jelly-like mucus) or nonmucinous.
Goblet cell carcinomas: Rare, aggressive tumors that share traits of both neuroendocrine and mucinous cells.
Treatments for appendix cancer include:
Appendectomy, in which surgery is done to remove the appendix, which is often sufficient for small or benign tumors.
Colectomy, which involves removal of part of the colon if the cancer is more advanced or is an aggressive type.
And HIPEC, which is also known as hyperthermic intraperitoneal chemotherapy, which is a specialized heated chemotherapy wash that is used inside your abdomen for mucinous tumors that have leaked or have spread.
