The proper diagnosis can be made only by a colonoscopy. While colon cancer is fatal and is better as early as it could be identified, Ulcerative Colitis is not fatal but doesn’t have a cure.

Colon Cancer vs Ulcerative Colitis

The difference between Colon Cancer and Ulcerative Colitis is that Colon cancer is a tumour on the colon wall, which is fatal. At the same time, Ulcerative Colitis is just the immune system’s reaction to Candida Albicans proliferation in the colon and is not fatal but incurable.

Colon Cancer vs Ulcerative Colitis

Colon cancer is a prevalent type of cancer, and still, there are no measures till now which can prevent it or precisely diagnose it at an early stage apart from colonoscopy.

If it gets severe, it is proven to be fatal and brings down the chances of living for five years to 8 per cent.

Ulcerative cancer has a lot of common symptoms to colon cancer, like fatigue.

It is generally considered an autoimmune disease that is the immune system after the body attacks itself. It is a lifelong disease that is incurable but at least not fatal.

AboutColon cancer is a tumour growth that is abnormal and is present on the wall of the colon.Ulcerative Colitis is a reaction of the immune system to Candida Albicans proliferation in the colon
SymptomsNarrow stools, fatigue, fluctuation in bowel system, bloated sensation, etc.Diarrhoea, Tenesmus, rectal bleeding, fatigue, weight loss, Anemia, etc.
CausesOvarian cancer, family history, Crohn’s disease, etc.Family history, smoking, low immune system, stress, etc
CureColon cancer is fatal, and if it has spread severely to the organs, then the chance of survival for five years lowers to 8%.Ulcerative Colitis has no cure but is not a fatal disease.
TreatmentSurgical removal of tumours, chemotherapy, radiation treatment are some common treatments for colon cancer.Medication and Surgery depend on the severity of the condition.

What is Colon Cancer?

Colon cancer is a common disease, and it is a growth of abnormal cells that gradually spreads to other organs of the body.

It is hard to identify it in the early stages, and therefore, its chances of becoming fatal increase even more.

Starting like a polyp or growth of an abnormal tumour on the walls of the colon, it gradually grows and after years becomes apparent.

It can have minor symptoms that include diarrhoea, changes in bowel systems, constipation, Malena, narrow stools or reduction in faeces, fatigue, unexpected weight loss, and bloating.

Colon cancer causes gripping and acute pain. Colonoscopy is a great way to detect colon cancer and an early stage. It is generated for many known and unknown reasons.

The most common cause of colon cancer is Hereditary, a family history of colon cancer, an ongoing or past case of ovarian cancer, Crohn’s disease, etc. It usually happens before 40 years of age.

After detection of colon cancer, if the polyps are few, then they can be easily removed during colonoscopy by a method known as polypectomy in this case.

Apart from this, surgical treatments that mean removing the colon part affected by surgery that is further followed by chemotherapy and radiation treatment are also considered for treating colon cancer.

Radiation treatment is brought into work when the surgery does not succeed.

What is Ulcerative Colitis?

Ulcerative colitis it’s a very similar appearing disease to colon cancer, and therefore, many times, people mistake it for cancer and vice versa.

Ulcerative colitis is generally regarded as an autoimmune disease in which the immune system attacks itself by reacting to the candida Albicans proliferation in the colon.

Its symptoms include Bowel movement, urgency and frequency in Bowel movements which are without or with blood loss, cramps, discomfort in the lower abdomen, fever, appetite loss, weight loss, diarrhoea, lethargy, anaemia, skin rashes, joint pain and problems, kidney problems, liver diseases, fatigue, diarrhoea, etc.

Since it has some of the symptoms that can also be seen in colon cancer, it is common to misjudge it.

It causes a lot of pain that comes in waves in the abdominal region and can be considered abdominal cramps.

There are a lot of causes that can cause ulcerative colitis that includes but are not limited to family history, exposure to infectious agents, low immune system, stress, and smoking.

Although once it is diagnosed by colonoscopy, it can be treated with medication or surgery.

It is a mild condition of ulcerative colitis that can be treated with medication, but surgery is the only option to cure it entirely.

Main Differences Between Colon Cancer and Ulcerative Colitis

  1. Colon cancer tumour grows on the wall of the colon, whereas ulcerative colitis functions the immune system in the colon region.
  2. Narrow stools, fatigue, and changes in the bowel system are some common symptoms of colon cancer. On the other hand, diarrhoea, fatigue, rectal bleeding, weight loss, appetite loss are common symptoms of ulcerative colitis.
  3. In colon cancer, there is gripping and acute pain experienced by the patient, whereas in ulcerative colitis, pain is experienced as waves in the abdominal region.
  4. Colon cancer is a fatal disease and cannot be cured if it develops to a severe stage, while ulcerative colitis may not be incredible but is not a deadly disease.
  5. Small cancerous growth called polyps in the colon region can be removed by polypectomy, but surgery is the only option for colon cancer if it increases. Ulcerative colitis can be treated by medication in the primary stage and best surgery in the higher setting.
