BOWEL CANCER
What is bowel cancer ?
Colorectal cancer is a common malignancy in
the gastrointestinal tract , and a third of the most common cancers every new
colon cancer patients in approximately 1.23 million worldwide . For the
majority of the age of onset of 40 years , 30 years of age account about 15 %
of events . See more males to female ratio of 2-3:1 .
The main symptoms of bowel cancer
There is no obvious early symptoms of colon
cancer , the progression of the disease can lead to irritation and changes in
bowel habits , it can be seen as diarrhea or constipation , sometimes
alternating diarrhea and constipation , and abdominal pain are common .
Secondly , colon tumors also meimbulkan
symptoms bloody stool without pain , usually the amount is not a lot of blood ,
sometimes bright or dark red , bleeding usually occurs intermittently , such as
if the position of the tumor is rather high , then the blood mixed with the
stool , sometimes bloody stools and also slimy .
With the passing of the disease , so that
the spread of the tumor into the bowel lumen stenosis caused by intestinal
obstruction , the patient's first symptoms of bloating , abdominal discomfort ,
and abdominal pain paroxysmal , hyperactive bowel sounds , constipation or
stool into thin ( shaped like a pencil ) and flatulence and water stops .
Advanced stage colon cancer often affects
surrounding tissues and organs , such as the bladder and prostate and other
nearby tissues , causing urinary frequency , urgency and dysuria . When the
tumor invasion of the lumbosacral plexus and lumbar sacral pain occur .
Causes of Colorectal Cancer :
1 . Genetic colon cancers have specific
genetic factors , family history of colon cancer are more prone to this disease
. Some intestinal adenoma is an autosomal dominant inheritance , high
heritability .
2 . Diets : in addition to some of the
foods that contain nitrites , cause of colon cancer is a long -term diet high
in fat is the main reason .
3 . Bowel disorders : acute and chronic
colitis , colon polyps , ulcers and other gastrointestinal disorders , which impair
the function of the intestine , which can cause colon cancer .
4 . The other diseases : schistosomiasis
and other parasitic diseases , can cause damage to the intestinal mucosa ,
causing ulcers , inflammation , there adenomatoid hyperplasia , and induces
colon cancer .
5 . Micronutrient deficiency : in
particular molybdenum , will increase the risk of bowel cancer .
How to diagnose colon cancer
With the increase in medical technology ,
current clinical diagnostic methods for colorectal cancer increased , including
the following manner :
1 . Examination including X - ray
examination of the gastrointestinal barium meal and barium enema complete . In
colon cancer patients with a barium enema is right . For smaller lesions can
also be found in the intestines of gas injection to gas double contrast barium
, check the fine .
2 . Colonoscopy
Sigmoidoscopy : straight type , up to 30 cm
, easy to examine , biopsy can be performed with direct vision , suitable to
inspect the following parts of the sigmoid lesions .
Colonoscopy : 120-180 cm long , can be bent
, can be observed throughout the intestine , to make electricity , coagulation
and biopsy can detect early lesions . It is difficult to diagnose the current
state examination can be used for this check .
3 . Ultrasound , CT scan : Relationship
location , size , and relationship with the surrounding tissue , lymph nodes
and liver metastases determine the specific figures .
4 . The CEA : carcinoembryonic antigen (
CEA ) has been measured generally , bowel cancer is the most important
examination of colon cancer . Generally considered to evaluate the therapeutic
effect and prognosis valuable and continuous determination of serum CEA can be
used to observe the effects of surgery or chemotherapy .
Stage Colon
If the patient has been diagnosed with
cancer , doctors must determine the stage of colon cancer . Doctors need to
conduct additional tests to determine the stage of cancer . Knowing the stage
of the cancer , it is important to determine the best method of treatment .
Stage 0: The cancer is at an early stage ,
cancer cells are only in the innermost lining of the intestine .
Stage I : Cancer invades many areas of the
intestinal wall .
Stage II : Colorectal cancer has spread
beyond the scope of the surrounding tissue , but did not spread to the lymph
nodes .
Stage III : Cancer has spread to the lymph
nodes but has not spread to other parts of the body .
Stage IV : The cancer has spread to other
body parts . The large intestine is easy to spread to the liver and lungs
How to treat colon cancer
Currently colon cancer using a combination
of therapies , including surgery , radiotherapy and chemotherapy , targeted
therapy , and others .
1 . Operation : Surgery is the primary
treatment for colon cancer . Stage 0 colon cancer treated with surgery ,
chemotherapy and preoperative and postoperative radiotherapy can be added or
traditional Chinese medicine .
2 . Radiotherapy and chemotherapy :
preoperative radiotherapy / chemotherapy can make the lesions shrink , increasing
the effects of the operation . Postoperative radiotherapy / chemotherapy to
kill the remaining lesions and reduce the recurrence and metastasis . For
patients with advanced-stage colon cancer , chemotherapy can be used as a
palliative treatment , improve patient quality of life and prolong survival
time . However , radiotherapy and chemotherapy for patients with nausea ,
vomiting and other side effects are obvious .
3 . Targeted therapy : Molecularly targeted
therapy is a new method of treatment , and has been proven effective ,
according to the different parts of the tumor , targeted anticancer drugs to
kill cancer cells and thus play a role , a small impact on normal tissue .
Compared with traditional chemotherapy , targeted therapies fewer side effects
.
4 . Therapeutic interventions : refers to
the exposure of the lesion does not occur surgery , blood vessels , skin , a
few millimeters in diameter to create small channels or existing pipe by the
body , the image ( angiography , fluoroscopy , CT , MR , ultrasound ) under the
guidance of treatment for the local treatment of traumatic lesions minimal .
Therapeutic intervention with minor injuries , simple , safe , effective ,
fewer complications and hospital stay time is shorter .
5 . Photodynamic Therapy : Photodynamic
therapy is the use of efficient photosensitizers and laser destroys cancer
cells , is a noninvasive therapy . This therapy is completely different from
surgery , radiotherapy , chemotherapy and immunotherapy , is a fast developing new
therapies and can be applied to the clinical treatment of colon cancer .
How to prevent colon cancer
Prevention of colon cancer first start of
the diet .
First of all diet, a reasonable combination
, intake of vitamins and trace elements , eat high-protein, high -fat ,
high-calorie foods .
The second should be noted that you should
leave the bad habit . Such as smoking , drinking , staying up all night ,
overeating , etc.
Third , we must pay attention to is to
actively treat constipation , ulcerative colitis , ulcers and other common
polypoid bowel disease .
Fourth , we must pay attention is to be
active , persistence , and increase immunity .
