Avastin® (bevacizumab) is a biologic medicine designed to target and inhibit vascular endothelial growth factor (VEGF), a key protein that stimulates new blood vessel growth in tumors. By blocking VEGF, Avastin helps starve tumors of the blood and oxygen they need to grow, slowing disease progression in people with metastatic colorectal cancer (mCRC).
Avastin is given as an intravenous (IV) infusion in combination with chemotherapy, typically every 2 to 3 weeks depending on your prescribed treatment plan. Treatment continues as long as your healthcare provider determines you are benefiting.
Serious side effects include: GI perforation, a hole that develops in your stomach or intestine, abnormal passage in the body, wounds that don't heal, serious bleeding, severe high blood pressure, kidney problems, infusion-related reactions, severe stroke or heart problems, and nervous system and vision problems. Common side effects are high blood pressure, too much protein in the urine, nosebleeds, bleeding, back pain, headache, taste change, dry skin, Inflammation of the skin and nose, and watery eyes. It’s important to review benefits and risks with your doctor.

Important Safety Information & Indication

Back to Top

[H3] Indication
[H5] Metastatic Colorectal Cancer (mCRC)
Avastin is approved to treat metastatic colorectal cancer (mCRC) for:
First- or second-line treatment in combination with intravenous fluorouracil–based chemotherapy
Second-line treatment when used with fluoropyrimidine-based (combined with irinotecan or oxaliplatin) chemotherapy after cancer progresses following a first-line treatment containing bevacizumab
Avastin is not approved for use after surgery was used as the primary treatment in patients with colon cancer which has not spread to other parts of the body.

[H3] Possible serious side effects
Everyone reacts differently to Avastin therapy. So, it's important to know what the side effects are. Although some people may have a life-threatening side effect, most do not. Your doctor will stop treatment if any serious side effects occur. Be sure to contact your health care team if there are any signs of these side effects.
GI perforation. A hole that develops in your stomach or intestine. Symptoms include pain in your abdomen, nausea, vomiting, constipation, or fever
Abnormal passage in the body. This type of passage—known as a fistula—is an irregular connection from one part of the body to another and can sometimes be fatal
Wounds that don't heal. A cut made during surgery can be slow to heal or may not fully heal. Avastin should not be used for at least 28 days before or after surgery and until surgical wounds are fully healed
Serious bleeding. This includes vomiting or coughing up blood; bleeding in the stomach, brain, or spinal cord; nosebleeds; and vaginal bleeding. If you recently coughed up blood or had serious bleeding, be sure to tell your doctor
Severe high blood pressure. Blood pressure that severely spikes or shows signs of affecting the brain. Blood pressure should be monitored every 2 to 3 weeks while on Avastin and after stopping treatment
Kidney problems. These may be caused by too much protein in the urine and can sometimes be fatal
Infusion-related reactions. These were uncommon with the first dose (less than 3% of patients). 0.4% of patients had severe reactions. Infusion-related reactions include high blood pressure or severe high blood pressure that may lead to stroke, trouble breathing, decreased oxygen in red blood cells, serious allergic reactions, chest pain, headache, tremors, and excessive sweating. Your doctor or nurse will monitor you for signs of infusion-related reactions
Severe stroke or heart problems. These may include blood clots, mini-stroke, heart attack, chest pain, and your heart may become too weak to pump blood to other parts of your body (congestive heart failure). These can sometimes be fatal
Nervous system and vision problems. Signs include headache, seizure, high blood pressure, sluggishness, confusion, and blindness

[H3] Side effects seen most often
In clinical studies across different types of cancer, some patients experienced the following side effects:
High blood pressure
Too much protein in the urine
Nosebleeds
Bleeding
Back pain
Headache
Taste change
Dry skin
Inflammation of the skin
Inflammation of the nose
Watery eyes

[H3] Avastin is not for everyone
Talk to your doctor if you are:
Undergoing surgery. Avastin should not be used for 28 days before or after surgery and until surgical wounds are fully healed
Pregnant or think you are pregnant. Data have shown that Avastin may harm your unborn baby. Use birth control while on Avastin. If you stop Avastin, you should keep using birth control for 6 months before trying to become pregnant

[H1] How is Avastin designed to work?

Avastin® (bevacizumab) is a tumor-starving (anti-angiogenic) therapy. Avastin is designed to block a protein called vascular endothelial growth factor, or VEGF. Normal cells make VEGF, but some cancer cells make too much VEGF. Blocking VEGF may prevent the growth of new blood vessels, including normal blood vessels and blood vessels that feed tumors.
Unlike chemotherapy that attacks the cancer cells, the purpose of Avastin is to block the blood supply that feeds the tumor. This can stop the tumor from growing.
[H4] Tumor before treatment
New blood vessels feed the tumor so it can grow and spread.

[IMG: Tumor before treatment]

[H4] Tumor with Avastin and chemotherapy
Avastin helps prevent blood vessels from reaching the tumor; this could starve the tumor.
However, in a study of mCRC patients who continued on Avastin for second-line treatment after a first-line treatment containing bevacizumab, tumors did not shrink.

Avastin® (bevacizumab) is a biologic medicine used to treat recurrent glioblastoma (rGBM) in adults whose brain tumor has progressed after prior treatment. It is designed to target and inhibit vascular endothelial growth factor (VEGF), a protein that helps tumors grow new blood vessels. By blocking VEGF, Avastin helps limit the blood and oxygen supply that rGBM tumors need to grow. Learn more about how Avastin is designed to work in recurrent glioblastoma.
Avastin is given as an intravenous (IV) infusion, usually every 2 weeks for rGBM, through a vein or a port placed under the skin. Your care team will determine your treatment schedule and may continue Avastin as long as your tumor is controlled and side effects remain manageable.
Like all medicines for cancer, Avastin can cause side effects. These may include high blood pressure, too much protein in the urine, nosebleeds, bleeding, back pain, headache, taste change, dry skin, inflammation of the skin, inflammation of the nose, or watery eyes. Serious side effects may include GI perforation, wounds that don’t heal, or serious bleeding. Talk with your healthcare team right away if you notice any new or worsening symptoms.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Medical Devices, Pharma & Biotech BS: Genentech (avastin.com)

https://avastin.com 📍 Industry: Medical Devices, Pharma & Biotech
21 BS / 100

A rare example of high-integrity communication forced by regulation but executed with precision. While the site is highly repetitive, it replaces traditional marketing BS with dense clinical data and surprisingly transparent limitations of the therapy. It is a ‘Substance-First’ site where the legal disclosures provide more forensic evidence than the promotional headings.

To further reduce the BS score, Genentech should reduce the verbatim duplication of content between the homepage and the mCRC sub-page to minimize concept repetition penalties. Adding direct outbound links to ClinicalTrials.gov identifiers for the referenced studies within the body text would improve the proof path score. The trust_theatre_flag could be neutralized by integrating a more robust, verified professional review system for HCPs. Finally, adding ‘Person’ schema for the lead medical directors or clinical leads would close the minor authority gap for individual expertise.

The website perfectly aligns with the Pharma and Biotech industry classification. Its content is strictly focused on therapeutic indications, mechanism of action (VEGF inhibition), and regulatory-mandated safety disclosures for the drug Avastin.

“The score of 21 is driven primarily by industry clichés and repetition. The Information Density and Semantic Coherence pillars are extremely strong, showing almost no fluff or drift. The score remains above 10 only because of the heavy use of template language and the high number of content repetitions across the four analyzed pages.”
