Colorectal cancer is otherwise known as cancer of the colon or the rectum. This can affect both men and women with age being a major risk factor. Majority of such cancers are seen to occur after age of 50 years.

Type: colorectal cancers can present as one of the following types: 

Adenocarcinomas are the most common type of colorectal cancers. These cancers begin in the cells making mucous and other fluids. Certain colorectal cancers begin as adenomatous polyps (adenomas) that turn cancerous over a period of time. This is precisely why the adenomas are regarded as pre-cancerous or pre-malignant.

Gastrointestinal (GI) carcinoid tumors, GI stromal tumors, primary colorectal lymphoma, leiomyosarcoma, melanoma & squamous cell carcinoma are certain other colorectal cancers

Carcinoid tumors: start in specialized cells that produce hormones, in the intestine.

GI Stromal tumors: start in the interstitial cells of Cajal (ICC), in the wall of the colon.

Lymphomas: start typically in the lymph nodes but they may also start in colon or rectum.

Sarcomas: can start in the muscle and the connective tissue in the walls of the colon and rectum.

Gender: it affects both male and female populace.

Etiology: mostly, the factors that are associated with increased risk of colorectal cancer include the following  

Age exceeding 50 years.

Racial & ethnic background such as African Americans, in the USA, are known to have the highest incidence of colorectal cancer, and mortality rates.

Low fibre and high fat diet. Excessive consumption of red meat (e.g. goat meat, beef, pork, lamb, or liver), processed meats, butter, refined grains, sweets, sugary drinks etc all can increase the risk of colorectal cancer.

Personal history of inflammatory bowel disease (IBD) (e.g. ulcerative colitis), Crohn s disease, adenomatous colorectal polyps, colorectal cancer etc all.

Family history of colorectal cancer or adenomatous polyps etc all.

Inherited syndromes such as familial adenomatous polyposis (FAP) and Lynch syndrome (hereditary non-polyposis colon cancer or HNPCC).

Sedentary lifestyle/ associated Obesity.

Type 2 diabetes.

Tobacco and alcohol abuse.

Features or symptoms can vary from person to person depending on the size and location of the tumour. Following are the signs & symptoms mainly -

Changes in bowel habits, diarrhea or constipation or an alternating diarrhea and constipation.

Occult/ blood in the stool, and 

Problems related to blood loss (e.g. anemia, weakness, fatigue, intolerance to exercise, shortness of breath, increased heart rate, chest pain etc all),

Abdominal discomfort (frequent gas/ flatulence, bloating, fullness, cramps, and pain), vomiting etc.

Unexplained weight loss,

Pain with bowel movement,

Feeling that bowel does not empty completely,

Stools are narrower than usual.

Diagnosis: Following are the diagnostics employed. Abnormal blood test results may be indicative of malignancy, but a follow-up imaging/ biopsy is always the gold standard for accurate diagnosis.
Blood: fecal occult blood test, Carcinoembryonic Antigen (CEA) assay values are raised, Hb/ RBC counts may be low.
Imaging: Colonoscopy, Endorectal Scan/ CT Scan followed by Biopsy clinches the diagnosis and the nature of the disease.
Apart from the above-mentioned barium enema X-Ray, USG, Chest X-ray, PET CT scan etc all help detect metastasis, if any. An increase in level of the serum tumor marker  CEA  is indicative of metastatic spread/ proliferation that can be ascertained through a PET CT scan.
Treatment: Conventional treatment includes surgery, radiation and chemotherapy as contextually appropriate. Simultaneously, an adjunctive/ integrative naturopathic treatment with suitable complementary & alternative medicines (CAM)/ therapies too can help improve clinical outcomes and facilitate recovery as feasible contextually.
Prognosis: preventive measures, earlier diagnosis and right early treatment is key for better prognosis and efficient/ effective therapeutic management. Usually, the chances of cure for an early stage cancer are more. Above-mentioned apart, recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all too.

Prevention: rightly said, prevention is always a better choice. Although genetic risks are difficult to modify, still an adherence to a Mediterranean diet, maintaining an ideal body weight and an active lifestyle with due emphasis on regular exercising (for at least 30 minutes daily), de-stressing and relaxation is highly recommended for prevention or reducing the risks of colorectal cancer. A healthy eating plate comprises essentially a low fat diet, fibre rich foods including whole grain cereals, green leafy vegetables cooked using healthy vegetable oils, fresh fruits of all colours as seasonally available and healthy proteins/ fats including fresh fish, poultry, beans, nuts etc all. It is advisable to limit milk/ dairy, preferably of low fat content, to 1 to 2 servings max daily. Although alcohol is optional and is not for everyone, the consumption of the same, if any, has to be strictly in moderation, and is best avoided. Smoking is to be avoided as well. Again, red meat, butter, refined grains, sweets, sugary drinks including carbonated beverages and other high calorie foods etc all, if any, are to be taken sparingly or are best avoided too. Apart from the generic preventive measures as mentioned above, certain pre-malignant conditions, of which adenomas are the most common, can be successfully treated with complementary and alternative medicines too.

Colorectal Cancer - In a Nutshell!

When dieting and exercising fail to help an obese person manage their weight, bariatric surgery may be suggested. One of the most popular types of bariatric surgery is a gastric sleeve surgery or sleeve gastrectomy. The main aim of this surgery is to reduce the amount of food that can be consumed in one sitting. It does not affect the amount of nutrients and fats absorbed from the food that has been eaten. A majority of the weight loss resulting from this surgery happens within 12-18 months.

A gastric sleeve surgery is a relatively safe, straightforward and short surgery. Prior to surgery, few patients would have been given a special diet.  This surgery is always  performed laparoscopically popularly known as keyhole route. More than half the outer side of the stomach is removed. The remaining part of the stomach takes the form of a tube. 

Though recovery from any surgery varies from person to person, most patients are able to walk and allowed sips of water by evening. Though certain amount of pain and discomfort is expected, this remains in bearable range with pain killers. Usually liquid diet is advised for 2 weeks followed by soft foods for 4 weeks.

You will notice that you feel fuller much faster and are able to consume a very limited portion of your normal food intake. It is essential to drink plenty of water to remain adequately hydrated and to prevent constipation.

On an average, this surgery can help people lose up to 70% - 100%% of their excess body weight. However, this depends largely on your understanding and compliance of post operative dietary changes. A dietician can also help you make right food choices, decide meal portions and address the right number of meals needed by your body. For long term weight maintenance it is important not to fall back to your earlier lifestyle and to maintain a positive attitude.

Gastric Sleeve Surgery - What Is The Process Of It?

Ovarian cysts are fluid-filled sacs in the ovaries, often in multiples, which are very common in women. This is absolutely different condition from polycystic ovaries. Most of them are benign and not indicative of an underlying problem. They produce no specific symptoms and even if detected, can be watched over a period of time. Treatment may be required only if there are serious symptoms or there is higher possibility of cancerous nature of the cyst. Read on to know more. 

Types 

Functional: There are two types in this. The follicular variety is when the egg that is ready for fertilization does not completely shrink and stays for a few more days before it disappears. Another variety, the luteal ovarian cysts are formed when after the release of the egg, there is blood filling up in the corpus luteum. 
Pathological: There are many types here   dermoid, cystadenomas, endometriomas, cancerous cystadenocarcinomas etc. These are worrisome and need to be treated. Both varieties, once identified, should be monitored. The functional variety, though may not cause a problem, can cause infertility and so necessitate treatment. 
Symptoms 

Any ovarian follicle larger than 2 cm can be called as an ovarian cyst. They are usually benign and do not produce any symptoms. However, if they turn pathologic or grow in size, they can cause various symptoms such as: 

Irregular menstruation 
Heavy bleeding 
Intermittent spotting 
Painful and/or frequent urination 
Severe, recurrent abdominal pain 
Infertility 
Abdominal bloating 
Constipation or loose motions 
Nausea, sudden vomiting 
Fever, dizziness, and weakness 
While cysts are often quiet and do not produce any symptoms, they can cause intermittent, nonspecific symptoms like above. If there is a family history of ovarian cancers in mothers, maternal aunt, Sisters, Grandmothers etc then women should have regular Gynaecological checkups to have a check done for ovarian cysts. 

Why go for laparoscopic surgery? 

Laparoscopic surgery is considered to be one of the most effective ways of treating the condition of ovarian cysts. During the surgery, problem causing non-cancerous cyst can be removed without harming the ovaries. In the case of cancer, both ovaries along with uterus etc may have to be removed. This decision is taken by the operating surgeon depending upon age of the patient, characteristics and nature of the cyst and future fertility desires of the patient. 
The patient is given general anesthesia during the surgery. After the surgery, one is suggested to rest for a day and may be permitted to return to normal activities within a day s time. However, one needs to avoid any strenuous activity for almost a week. 
While some cysts can be watched for years, others need treatment. This would be specifically true in cases where the couple is facing infertility issues or if there is a higher possibility of cancerous cysts. Such cysts need urgent intervention and should be monitored by a gynecologist with an experience in oncology. There are few blood tests that are needed to be done to know the nature of the cyst if it is benign or cancerous.

Ovarian Cysts - Ways Laparoscopic Surgery Can Help! 

The kidneys are primarily responsible for filtering blood and removing waste from the body. They also regulate the fluid and electrolyte balance. If the kidneys stop functioning, a patient may need to undergo dialysis or have a renal transplant. Many patients prefer undergoing a transplant as it offers a better quality of life in the long run.

A kidney transplant can be described as a procedure to replace one s own kidneys with a donor's kidney. In case of kidney transplant, there are two types of donors. The human body can function with one healthy kidney and hence family members and friends of the patient may choose to donate a kidney. Else, a kidney may be sourced from recently deceased donors who have chosen to donate their organs after death. In both cases, it is important that the donor kidney match the patient s blood and tissue type.

A renal transplant surgery usually takes about 3 hours. The donor kidney is placed in the abdominal cavity and connected to the patient s arteries, veins and bladder. Usually, the donor kidney begins functioning immediately. The patient s own damaged or diseased kidneys may not be removed unless there is a severe infection, cancer or a diagnosis of large polycystic kidneys.

The patient will need to be hospitalized for a few days after the surgery. In some cases, dialysis may be needed if the kidneys are unable to produce urine. In addition diuretics and other medication may be needed to remove excess water and salt from the body. Medication will also be prescribed to suppress the immune system so that the patient s body does not reject the donor kidney. These medications typically need to be taken for the rest of the patient s life.

A renal transplant is considered a relatively safe procedure. Less than 20 out of 100 people reject a donor kidney. However, there are a few other risks involved. These include:
  Bleeding
  Severe infection
  Failure of the donor kidney
  Reaction to anesthesia
  Increased risk of infections due to suppressed immune system

Kidney transplant is not advised for people suffering from diseases such as cancer or any significant lung or heart disease. If the patient is suffering from an infection, he or she may be advised to wait until the infection subsides before undergoing a renal transplant. A renal transplant may seem to be an expensive procedure but in the long run, this can work out to be more budget friendly than dialysis.

Renal Transplant - What Should You Know About It?

The cancer of the bladder (an organ in the pelvic region that stores urine) is known as bladder cancer. This cancer begins in the cells that line the inner portion of the bladder. Though it usually affects the aged, bladder cancer can develop in people across other age groups as well. It is important to undergo frequent check-ups even after the condition has been cured, as there always remain chances of a relapse.
There are three types of bladder cancer:
1. Squamous cell carcinoma: Squamous cells appear in the bladder in response to any infection, which, with time, can become cancerous.
2. Transitional cell carcinoma: These cells are present in the lining of the bladder. They contract when the bladder is empty and expand when it is full. These cells are also found in the urethra, hence there are chances for the cancer to develop in the urethra as well.
3. Adenocarcinoma: Adenocarcinoma forms in the mucus secreting cells in the bladder.

The symptoms of bladder cancer are:
1. You may urinate frequently
2. Frequent backaches
3. You may experience pain during urination
4. Pain in the pelvic region
5. There may be presence of blood in the urine

There is no known cause of bladder cancer. However, certain factors such as smoking, infection and exposure to chemicals are known to trigger it. The risk factors of bladder cancer are:
1. Age: The risk of bladder cancer increases with age, it usually affects people who are above 40 years of age.
2. Smoking: Smoking releases toxins in the body that get stored in the urine. These can damage the inner lining of the bladder and lead to bladder cancer.
3. Gender: Men are more likely to develop bladder cancer as compared to women.
4. Chemical exposure: Exposure to certain chemicals such as arsenic increases your risk of bladder cancer.
5. Chronic inflammation of the bladder: If you suffer from chronic infection of the bladder, then the risk of squamous cell carcinoma increases significantly.

Bladder Cancer - 5 Things That Put You at Risk

Menorrhagia is a condition that is marked by heavy menstrual bleeding during the monthly menstrual cycles. Most women have a unique bleeding pattern during that time of the month with the flow going up and down over the first few days. Yet, for many women, the bleeding becomes consistently heavy during all the days of the period, during which the period itself may get extended by a few days. If this pattern continues to occurs, one must get it checked out by a doctor at the earliest. Here are a few ways in which this condition may be treated.

Factors considered during treatment

Before the treatment starts, and during the diagnosis stage, the doctor will take a look at a number of factors so that the correct form of treatment may be prescribed to the patient. To begin with, the doctor will take a complete medical history of the patient, including the family history to ascertain whether or not there may be a genetic problem at play. Further, the future childbearing plans of the patient will also be taken into consideration in such cases so that the treatment method does not hinder such plans. Also, the doctor will also try and understand the effect of the symptoms of this condition before prescribing any particular medication and surgery.

Medication

Iron supplements and non-steroidal anti-inflammatory medicines will be prescribed for the patient to bring down the level of inflammation and restore the production of blood, which will make up for the rapidly flowing blood from the body. This will also prevent the risk of anemia. Oral contraceptives, tranexamic acid, oral progesterone and hormonal therapy can also help in such cases.

Dilation and curettage

This procedure is also known as D&C, and it basically helps in dilation or opening up of the cervix so that the doctor may suction the tissue from the uterine lining. This tissue is usually known to bring about excessive bleeding.

Uterine artery embolisation

This is a procedure which shrinks any existing fibroids that may be the cause behind excessive bleeding. In this procedure, the uterine arteries are blocked and the blood supply to the same is cut off so that the fibroids do not get a chance to grow and cause unnecessary pressure that may lead to excessive bleeding.

Hysterectomy

This is a surgical procedure that removes the cervix as well as the uterus, and is usually the last resort followed by most doctors. In such cases, the doctor will first ascertain whether or not you plan to have any children in the future. Additionally, the ovaries may also be removed if the condition has spread too much to be contained sufficiently.
