To cope easily with the struggle of fighting colorectal cancer cannot be done overnight. A lot of people who acquire this disease can easily become depressed upon learning of the disease. Hence, friends and family should serve as a solid support system to their afflicted family member or friend so that they can also be eased of the severe emotional pain. Being known as the third most popular type of cancer worldwide, it is also a leading health problem in the US.

What Is Colorectal Cancer?

Colorectal cancer is the type of cancer that affects hugely the big bowel and the rectum, which are both lower parts of the digestive system of our body. Somehow, the main cause of this cancer is still considered to remain undefined but it is observed that if the disease runs in the family, then it is most likely for any member to have it.

Colorectal Cancer Symptoms

Early symptoms of colorectal cancer may include the presence of blood in the stool or the inability for motion pass which could mean blockage of the colon pathway. A lot more of the early symptoms can also include the more frequent occurrence of diarrhea, undefined stomach pain, and even constipation. Sudden weight loss without even going through some serious form or diet or exercise should also be something to be suspicious about.

Treatment for Colorectal Cancer

The degree of treatment for colorectal cancer will vary according to the stage of the colon cancer that one has. It also matters if the colon cancer that a person has is something that has just reoccurred. But above anything else, the overall state of the patient’s health is another determining factor for the treatment.

For those who are aware of their family history of this colorectal cancer, it can be advisable to go through an early screening for it; for there are greater chances of being healed when colorectal cancer is detected early on. The level of being cured through surgery at this stage can still reach up to ninety percent.

Signs of Colorectal Cancer

For sure signs of colorectal cancer, you must watch out for the following instances:

• When you suffer in your back passage a bleeding which is undefined
• Consistent changes in your bowel movements and activity can also be a huge sign
• An undefined presence of lump in the tummy region
• Paleness and exhaustion
• If you seem to be suffering from these signs for about four to six weeks now, then you should secure an appointment with your doctor

You must bear in mind that once you detect the signs of bowel cancer early on, you can have greater chances of being successfully treated. Hence, if you suspect some early signs and symptoms, then you must definitely have them checked. There is nothing wrong in believing the usual thought that prevention is the best cure to any kind of disease. You are the only person who can help yourself best in the first place so that you can start living a healthier life in the future.

Scientists state that they have created a very powerful PSA (prostate specific antigen) which shall distinguish the patients of prostrate cancer who could recidivate after their treatment. In a research which was announced this week in PNAS journal, the examination showed to be three hundreds sensitive than the other PSA examinations which are commercially available.

The researcher from Northwestern University, Chad A. Mirkin has invented this test and he is also the co-founder of the company which is going to market it. He explains about the molecular technique, based on nanotechnology. The test shall indicate men whether prostate cancer they have would reappear after their surgery very early than the test which are available at present. The first thing which was proved by their research was that everyone will have a calculable PSA level after removal of prostrate. This was not possible to measure using current tests.

While the benefits of calculating PSA in while screening for the existence of prostrate cancer is queried, there is a mild discussion that increasing levels of PSA following the treatment auspicate reoccurrence. But PSA is usually not detectable for many years after removal of prostrate surgically even with men who will relapse eventually. If we measure the PSA level after completion of surgery using normal tests, the level of PSA will be 0. Men have to wait for another 5-7 years to find out whether the cancer would return back.

Working Of The Test

This test was invented by Mirkin and his co-workers which make use of very minute golden nano particles to find out the earlier immeasurable PSA levels in blood of the patient. The scientists marked the nano molecules using 1000s of DNA strands combined with certain antibodies that can identify PSA. For each captured PSA molecule, 100s of DNA strands were freed as per Mirkin.

In the newly issued studies, the serum samples which were gathered from eighteen patients with prostrate cancer who removed their prostrates surgically got analyzed both using the normal test available now and the test based on nano-particles. The nano molecular test was capable of detecting the rise in levels of PSA in few men very earlier when compared with the standard test which is commercially available now. Mirkins stated that according to the study which involves two hundred and fifty patients treated surgically is under progress to ensure the findings of the research.

Second Opinion

The spokesman from American Cancer society Mr. Durado Brooks stated that the findings are good but in preliminary level. He stated that even if the bigger study is confirming that the nano-molecular state could accurately spot out patients whose prostrate cancer would relapse after surgery; there are not clear clinical advantages for this test. It’s because there are not enough treatment choices for men who have repeated prostrate cancer.

We are now sure that the increasing PSA level after the treatment could indicate the relapse of the disease, but we are still not aware that if the finding it earlier or even after 3 years will make significant differences with the results.

Seven symptoms often linked with ovarian cancer, has beer stated by doctors as per the new research in United Kingdom, falsifying the opinion that it’s a silent killer and there are no sufficient clues till the progressed stages. As per William Hamilton, who is consultant at Bristol University, ovarian cancer can be understood easily, if we look out for these symptoms, and it is the cause for four percent of all types of cancer in women. It has the worst medical prognosis when compared to other gynecologic cancers.

Study Details on Ovarian Cancer

In the research, Hamilton along with his team members assessed 212 women who were above age of forty, by diagnosing them for ovarian cancer and equated the results with that of thousand and sixty healthy women. They all went to thirty nine different doctors’ hospitals in Devon region of UK.

The research crew evaluated the medical reports for 1 year earlier to the cancer diagnosis and also performed the same analysis for healthy women. They observed the symptoms which were complained by them and the time.

Findings of the Study on Ovarian Cancer

There were 7 symptoms often linked with ovarian cancer as below :

1. Frequency of Urination
2. Abdominal distension
3. Pain in Abdomen
4. Rectal bleeding
5. Postmenopausal bleeding
6. Appetite loss
7. Bloating in Abdomen

The research crew computed the predictive values for every symptom i.e., the probability that with a particular symptom the women could really suffer from ovarian cancer. They symptoms had very low predictive values which were less than 1 percent other than the abdominal distention which had 2.5 percent of predictive value.

The 2.5 percent indicated one woman among forty having that symptom will actually suffer from ovarian cancer, which is a reasonably high value as per Hamilton. It is approximately same as risk considering lung cancer with the symptoms of blood while coughing or similar to colon cancer when blood is passed rectally. When the analyzed further, they found that 3 symptoms, abdominal distension, frequency of urine and abdominal pain are observed 6 months earlier to diagnosis and very well linked with ovarian cancer.

Symptoms and Sharing of Ovarian Cancer

Women frequently use bloating to refer distension, as per Hamilton’s report. But experts consider that distension is generally progressive growth in size of abdomen and bloating is a sporadic decrease and increase. Under present U.K. policies, abdominal distension cannot be considered as a symptom which requires immediate investigation.

Bloating is more probable to exist in women having ovarian cancer in United States, when compared with other women, according to American Cancer Society. When any woman, says that she has bloating, she will be asked to undergo physical examination and also blood test (CA-125) which computes the amount of proteins in the blood of women suffering from ovarian cancer or undergo a transvaginal ultrasound test. These tests are done mostly to women with more risk considering ovarian caner, like people who have family history for the disease.
